We've noticed this variation behaviour in the past when using
boost::mutex. Under the hood on Windows it uses a critical section
which I believe is recursive. Not sure if the rewritten version of
Boost.Threads will do the same.

Sorry, but all I can do is confirm the behaviour. I believe the
Boost.Threads concept documentation for mutex and scoped_lock say that
attempting a recursive lock gives "undefined behaviour" rather than
definitely deadlocking.
