[JDEV] core dump with 1.0.1 on redhat 6.2 -- back trace

[Benjamin Kahn]

	When giving a backtrace with gdb, you MUST use this order to
getting it:

$ gdb jserver
(gdb) handle SIGUSR1 nostop noprint
(gdb) run -D
:
.
***crash***
(gdb) bt

	If you skip the handle command, all your backtraces will look like
the message below.  That's because Jabber uses PTH which uses SIGUSR1 to
handle tread switches and GDB flags that as an interesting event.  (The
other way is to just "cont" until you get a real crash.)
