If you don't use boost::condition with the mutex a null_mutex type 
can be coded up with out any effort at all (and in fact such a mutex 
can not be safely used with a condition variable).  For that reason 
I've not included this type in Boost.Threads.  It's important that we 
get Boost.Threads accepted quickly, and this means I need to keep the 
library "minimal but complete" for the initial submission.  There are 
numerous other types that I expect to add to Boost.Threads later, and 
this includes a null_mutex.  In the mean time I'd suggest either 
coding your own or using conditional compilation instead of the 
Strategized Locking pattern.
