    Just as an aside, I seem to remember POSIX making a distinction between
    'global' signals and 'per-thread' signals.  Something about a signal that
    cannot be handled by a thread is queued globally and then processed by
    the first thread that can take it, or something like that.

    This would imply that we need to have a two-level signal delivery 
    architecture (lwp layer and process layer).
