I noticed same thing last week--a multithreaded program deadlocks with 
multiple threads waiting for write lock but no one holding it.  It was 
not immediately clear to me why.

This was reproduced on win32, linux and solaris, so it appears to be 
read_write_lock specific problem.  Underlying primitives (mutex and 
condition) work fine on all platforms.

The same code worked fine with boost 1.32.
