No, the behavior is operating system dependent.
See e.g.
http://boost.org/doc/html/thread/concepts.html#thread.concepts.locking-strategies

"With an unspecified locking strategy, when a thread attempts to acquire 
a lock on a mutex object for which the thread already owns a lock the 
operation results in undefined behavior."

Boost thread currently only provides: "unspecified locking strategy."
