[boost] named_condition_any not working.

Hello! I tried to use into my code an interprocess mechanism like producer/multiple consumers with named_sharable_mutexes. I found out that named_condition_any is not working with any kind of scoped locks. Neither with sharable_mutex or simple named_mutex. It takes the lock successful but cannot unblock another process when notify is called. I used linux, gcc 4.8, just basic build, linking with pthreads. Is this a known issue to you because I couldn't find any info related on the Internet? Maybe I can take a look next week what is in there... Adrian
