In theory, you could use Boost.Interprocess, but those are prepared for
shared memory and not optimized for a single process inter-thread
synchronization. I would recommend using Boost.Thread.

I don't know, you could use catch that exception and print what it says.

It should be, but I think a more efficient semaphore could be built for
Boost.Thread. I know some consider semaphores risky, but for many tasks
(like drivers, or signals) it's the only mechanism allowed by the OS to
notify events to other threads.
