Multiple thread handling

One of the salient features of the QNX Neutrino RTOS is the ability to use threads. By using multiple threads, a resource manager can be structured so that several threads are waiting for messages and then simultaneously handling them.

This thread management is another convenient function provided by the resource manager shared library. Besides keeping track of both the number of threads created and the number of threads waiting, the library also takes care of maintaining the optimal number of threads.
