        Unix signals are used (generally) for two things:
      </para><list type="bullet"><item><term>
          Asynchronous alerts about events that occur within a process, such as 
          illegal instruction (<see cref="F:Mono.Unix.Native.Signum.SIGILL" />),
          floating point exception (<see cref="F:Mono.Unix.Native.Signum.SIGFPE" />),

          etc.
        </term></item><item><term>
          Asynchronous alerts of external "events", such as
          termanal hangup (<see cref="F:Mono.Unix.Native.Signum.SIGHUP" />),
          keyboard interrupt (<see cref="F:Mono.Unix.Native.Signum.SIGINT" />),
          broken pipe (<see cref="F:Mono.Unix.Native.Signum.SIGPIPE" />),
          program-defined actions 
          (<see cref="F:Mono.Unix.Native.Signum.SIGUSR1" />,
          <see cref="F:Mono.Unix.Native.Signum.SIGUSR2" />),

          etc.
        </term></item></list><para>
        The key nature about signals is that they are asynchronous.  In a
        single threaded program, when a signal occurs the executing thread is
        "hijacked" (no matter what it was previously doing) in order to
        execute a (optionally registered) signal handler, and then the thread
        resumes what it was previously doing (if possible; the signal handler
        may abort the process as part of its execution).
      </para><para>
        In a multi-threaded program, a thread is selected at random among the
        threads that can handle the signal, and that thread is hijacked to run
        the signal handler before continuing (while the other threads continue
        to execute in ignorance that a signal is occuring).
      </para><para>
        Tradtionally, <see cref="M:Mono.Unix.Native.Stdlib.signal" /> is used
        to register a signal handler for a signal, and the registered handler
        is invoked when the signal is generated.  However, due to the
        "hijacking" nature of the signal handling process, what the signal
        handler could do is <i>severely</i> restricted: it must not invoke
        non-reentrant library functions, and can only modify global data and
        execute a limited set of system calls such as 
        <see cref="M:Mono.Unix.Native.Syscall.read" /> and
        <see cref="M:Mono.Unix.Native.Syscall.write" />.
      </para><para>
        Managed code throws an additional wrench in the works, as the platform
        invocation mechanism is neither reentrant nor signal safe. Consequently,
        managed code <i>can not</i> be safely and reliably used as a signal
        handler (as would traditionally be done with <c>signal</c>(2)), thus
        the <see cref="T:Mono.Unix.UnixSignal" /> type.
      </para><para>
        A <see cref="T:Mono.Unix.UnixSignal" /> instance represents the number
        of times that a Unix signal has been emitted.  That's all.

        In order to operate, this class uses an internal unmanaged signal
        handler to represent the count information.  Consequently, the count
        will only be updated as long as no other mechanism is used to change
        the registered signal handler, such as
        <see cref="M:Mono.Unix.Native.Stdlib.signal" /> or
        <see cref="M:Mono.Unix.Native.Stdlib.SetSignalAction" />.  If you use

        <see cref="M:Mono.Unix.Native.Stdlib.SetSignalAction" /> for the same
