DBX and signals

[Charles J Wilde]

I have an application which calls a device driver on the Sun.  The
application disables all maskable signals with a sigsetmask() before
calling the driver routines.  Unfortunately, this causes dbx to hang on
the sigsetmask call.  What signal(s) is dbx interested in?  I assume I'll
have to change my mask value if I want to run dbxtool on this application.
