	uh, not really.  When I started the linux compat on alpha code I
started to implement the rt signal stuff by figuring out what the
linux kernel did (utsl! ugh).  I never finished it because I needed a
way to store per-process emulation specific data (which we didn't have at
the time) and, while playing with ways to do that, got distracted by
something else.
	I don't know if anyone else did any work on it (brief look at cvs logs
doesn't make anything obvious stand out).  If not don't expect that code to
