Going back to the original problem, perhaps we could have fixed
it instead by acquiring a lock around all plugin callbacks, and
ensuring that plugin_cleanup also acquires the same lock. The
lock would normally be uncontended so it shouldn't cause any
performance issues. That would be a fairly simple revert of
63f0eb088 + alternate fix.
No actually that would serialize everything. Some sort of mutex
primitive, I think a shared/exclusive lock with the exclusive lock
being taken in plugin_cleanup.
