Seems like it's too much trouble.. I mean, we're removing semaphores
anyway and down_trylock with them. I'll agree with Andrew down_trylock
removal is pretty glacial. It's cause there aren't many of them and most
of the ones I've looked at are in strange locking schemes, which makes
them difficult to remove.. 

I'm not against your changes, but if it's going to cause problems I'd
rather people focus on mutex_trylock instead.
