Log message:
Replace the hand-rolled semaphore with a read-write lock
This was sitting in my tree for many a month and since the introduction
of interrupt threads, the interrupt vs. process context interlock became
irrelevant. Taking uncontended write locks while "cold" doesn't look
like a big deal as well.
