Unfortunately, there is no apparent way for me to set up Ups
(that I'm aware of) to ignore this signal.  When I try to
expand the signal list in the Ups window, only up to signal
31 is displayed.  In any case, it's the subsequent thread(s)
that I care about, so if I had no access to the spawned threads,
then I would still not be able to debug properly.

Since I know very little about the mechanics of threading (be it
in Solaris or Linux), I will assume it's a fairly complex one to
deal with, particularly for a debugger.  So, should I assume that
that functionality will not be soon available under Ups?
