I agree. I'd rather _keep_ the completions, and get rid of the semaphores, 
so I think the whole fundamental patch here under discussion is broken.

We should do:
 - continue replacing semaphores that are used purely for mutual exclusion 
   with mutexes.
 - probably add support for completions to do counting
 - and then eventually just do the _reverse_ of what the current patch 
   does, namely replace the existing counting semaphore usage with 
   completions.

Hmm?
