What Ben says is true. For various reasons, including this one, it's
usually far better to derive a class from omni_thread, rather than
creating a base omni_thread instance, passing in a function pointer.
That way, you just provide a run() member function to your class, and
it gets called when the thread is started.

Cheers,

Duncan.
