what is the general criterion (if one exists) one should use when 
choosing a synchronization object to use in kernel mode code?

I ask you this question, because a possible race condition was reported 
by Gé in the LPC code.
As a preliminary step in fixing that, I introduced a FAST_MUTEX to queue 
threads that use the LPC facility.
Now I see that you use an ERESOURCE to fix the same problem in the CM.
