I think this is an excellent idea.

About 4 years ago, we (the FreeBSD project) wore significant pain
whilst the signal space was expanded from 32 to 128 signals.  In that
time, precisely one additional signal has been defined.  There doesn't
seem to be any reason for not supporting another one or two USR signals.
