Really, the only answer to your question is that Pth provides cooperative
multi-tasking. It's up to you to decide when you want your threads to yield
the CPU to other threads that might be able to run. One way to do this is to
put 'pth_yield' calls in strategic places. If you really need I/O
concurrency, you really shouldn't use Pth and on FreeBSD 4, you should use
the LinuxThreads port.
