Log Message:
More locking protocol fixes.  Protect pool_head with a spin lock (statically
initialized).  This lock also protects the "next drain candidate" pointer.

XXX There is still one locking protocol problem, which should not be
a problem in practice, but is still marked as an issue in the code anyhow.
