Hi, I was implementing a kind of server using shared memory.
The server should keep idle, waiting for a request and I do this by
waiting on a condition variable, of course.

I then noticed my fans running high when I let the server waiting a
little longer while testing and discovered this happens simply because
of some busy loop implementation for condition waiting.

Is there any reason for that?

Given the interprocess library age, there's no way for implementing a
non-busy interprocess condition variable waiting available?
