------------------------


I am trying to debug some problems I have with the
beta 2, and in the process wanted to run sge_execd
and sge_shepherd under the debugger.  That didn't
work.  After a while I realised it is because the
application blocks the SIGTRAP signal.

In sig_handlers.c actually all signals but a
selected set is blocked.  I don't see why this is
a good idea, but maybe I miss something.  In any
case I think allowing SIGTRAP would make sense.

I've enabled SIGTRAP for the shepard in our maintrunk. We need to verify that
this doesn't lead to any negative effects.
