[BProc] deadlock with 2.4.21/3.2.6

[Nicholas H. <he...@se...>]

Howdy~
	I am back to torturing bproc again, just trying to make sure a kernel
upgrade is going to be stable. Attached is a tar.gz with a script to run
remote_fork (.c included). There is a 'NODES=' section at the top to
edit for your nodes to use.

If you do a './run.sh 10000000' ( 10 million iterations ), at some
point, usually 1.5 million, the head node will hard lock -- not even
nmi_watchdog can rescue it.

If you have a way to rescue a kernel from this hard of a lock, I would
love to know about it, so I could give this bug a whirl, but otherwise I
am pretty stuck.
