OSLockSpin(??)

When investigating the NSD server thread stacks, a specific stack always showed to be the most CPU consuming thread. Using OS tools, the thread always calls OSLockSpin().

OSLockSpin(??) is a low level function in Domino code used to grab a mutex from the OS to prevent other threads from doing the same operation at the same time.
