[PATCH] fix error sending signal to dead process

Subject: [PATCH] fix error sending signal to dead process

 
Using insight-7.4.50 (cvs snapshot 20120403), continuing or stepping
after a fault (i.e. segfault) occurred results in sending a signal to
the dead process.
This is due to hook gdbtk_annotate_signal() trying to get thread_info
structure with a null pid.
Continuing in the same insight session (by re-running the program)
finally ends in insight segfaulting.
 
The attached patch fixes this problem. It simply do not pass signal to
tcl if the pid is null.
 
Cheers,
Patrick
