Log:
When going to sleep, we must save our SPL so that it does not get
lost if some other process uses the lock while we are sleeping. We
restore it after we have slept. This functionality is provided by
a new routine interlocked_sleep() that wraps the interlocking with
functions that sleep. This function is then used in place of the
old ACQUIRE_LOCK_INTERLOCKED() and FREE_LOCK_INTERLOCKED() macros.
