Just an update for everyone. Back in September, I worked with Ion to get a
configurable timeout feature built into interprocess_mutex. It will throw a new
timeout exception if locked for more than a set period of time (configurable at
compile time). This will fix the issue of message_queue and
interprocess_condition hanging up on termination of the dependent process.
Hopefully this feature will be available in Boost 1.48.
