I did not mean to imply that the null_mutex was required prior to
threads being submitted. At the moment I'm just trying to flesh out
the requirements and start on layer 1 design.
If I do need a null_mutex, I can easily roll my own and will happily
submitt it for addition to threads as and when you want it.

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.
