regarding testing of modular sysv IPC

I've now gotten a pile of success reports and suggestions for tests I
can do - thanks people! - but I haven't heard much if anything about
the cases I'm worried about: races between module load/unload and
create/delete of IPC objects, semaphore undo requests that linger
after the module is unloaded, resource leaks, and use miscounts. In
other words, I'm looking for problems with the module code, not IPC
itself.

There are four KERN_ERR printk's in the patch. If the patch is
correct, it should be impossible to trigger any of those printk's.
I'd like testers to focus on verifying that this is indeed impossible.
I have done some testing of this myself, but the more people hit it
the better.

I'm particularly interested in results for SMP systems, which I cannot
test myself.

Thanks again for all the help.
