I actually ran into the same issue. I solved it by using file locks, 
instead of named mutexes, because the file lock will be released when the 
process crashes.

Hello, 
I am working on application where several multi-threaded processes are 
attempting to acquire a lock on the shared memory files managed via boost 
interprocess. 
It appears that if one of these processes dumps a core while holding a 
lock on the shared memory file, all the other processes end up waiting for 
this lock to be released. 
Any ideas on how this can be overcome? I want to ensure that when a 
process that is holding the lock dies, it should ensure that the lock is 
released. 
Thanks,
Raj
