That system has 64 cpus. ps -ef attached.

I think so too :-)

No problem, I'll just get the races closed up in the existing version.
I think we basically have two classes of users here - one that the
existing workqueue scheme works well for, high performance work
execution where CPU affinity matters. The other is just slow work
execution (like the libata pio task stuff), which would be better
handled by a generic thread pool implementation. I think we should start
converting those users to slow_work, in fact I think I'll try libata to
try and set a good example :-)
