Yes, this problem seems to have begun after the upgrade from 6.1-RELEASE
to 6.1-RELEASE-p1, though it's hard to see the connection.

Excuse my ignorance - I take it I need to

	o start firefox normally
	o run gdb as above
	o invoke the crash situation
	o then ... ?

I'm just hoping that there's enough cpu left to save something at that

I probably don't - I added this after reading /usr/src/sys/conf/NOTES and
it hadn't bitten me until maybe now.  I'll recompile the kernel with
SCHED_4BSD before I carry on.
