     Type:  Bugs                  |      Status:  new         
Milestone:  Boost 1.41.0          |   Component:  interprocess
  Version:  Boost 1.39.0          |    Severity:  Problem     
 Keywords:  file_lock open close  |  
----------------------------------+-----------------------------------------
 An exclusive file lock is lost if the same file is opened and closed else
 where in the code.

 The attached example was complied like this:

   g++ -o boost_file_lock_test boost_file_lock_test.cpp
 -I<path/top/boost-1_39>/include/boost-1_39/

 Running two instances with in 30 seconds demonstrates the bug.  Both
 instances print 'Acquired lock' when one should print 'Could not acquire
 lock' and exit.

 This affects, at the very least, Ubuntu 9.04 Linux but most likely other
 Linux systems and possibly other platforms.
