Milestone:  To Be Determined      |   Component:  thread     
  Version:  Boost 1.51.0          |    Severity:  Showstopper
 Keywords:  mutex deadlock VC7.1  |  
----------------------------------+-----------------------------------------
 I'm using mutex and scoped_lock to lock and unlock it. Once a thread locks
 the mutex, it never gets  unlocked, even though the lock goes out of scope
 and even when the thread terminates.
 As a result it causes a deadlock.

 The problem shows only when the operation the thread is doing is long
 enough to allow context switching between the threads.

 Problem appears on Visual Studio 2003 (VC7.1)
