I always work at a distance in case thing blow...

My patch isn't a perfect solution.  While EPROTO is the most
frequent error when resuming, I have also seen EINVAL and ESRCH.

Then, if I pound real hard trying to make vla6.x3g fail:

(gdb) r
Starting program: /mnt/gnu/gcc/objdir/hppa2.0w-hp-hpux11.11/libgomp/testsuite/vla6.x3g 
vfork: Resource temporarily unavailable.
(gdb) r
Starting program: /mnt/gnu/gcc/objdir/hppa2.0w-hp-hpux11.11/libgomp/testsuite/vla6.x3g 
vfork: Resource temporarily unavailable.
...

-bash-3.2$ ps -ef|grep vla|wc
73 585 8121

For some reason, the vla6.x3g processes aren't exiting when run under gdb
in spite of the fact that gdb says they exited normally.

I'll look at your patches.
