-//  boost::detail::lightweight_mutex meets the Mutex concept requirements
-//  See http://www.boost.org/libs/thread/doc/mutex_concept.html#Mutex
-//
-//  * Used by the smart pointer library
-//  * Performance oriented
-//  * Header-only implementation
-//  * Small memory footprint
-//  * Not a general purpose mutex, use boost::mutex, CRITICAL_SECTION or
-//    pthread_mutex instead.
-//  * Never spin in a tight lock/do-something/unlock loop, since
-//    lightweight_mutex does not guarantee fairness.
-//  * Never keep a lightweight_mutex locked for long periods.

-//  Note to implementors: if you write a platform-specific lightweight_mutex
-//  for a platform that supports pthreads, be sure to test its performance
-//  against the pthreads-based version using shared_ptr_timing_test.cpp and
-//  shared_ptr_mt_test.cpp. Custom versions are usually not worth the trouble
-//  _unless_ the performance gains are substantial.

 //
-//  Be sure to compare against a "real" pthreads library;
-//  shared_ptr_timing_test.cpp will compile succesfully with a stub do-nothing
-//  pthreads library, since it doesn't create any threads.
