Create a work request for a callable and attach callbacks.
A work request consists of the a callable to be executed by a
worker thread, a list of positional arguments, a dictionary
of keyword arguments.
A callback function can be specified, that is called when the
results of the request are picked up from the result queue. It must
accept two anonymous arguments, the WorkRequest object and the
results of the callable, in that order. If you want to pass additional
information to the callback, just stick it on the request object.
You can also give custom callback for when an exception occurs with
the exc_callback keyword parameter. It should also accept two
anonymous arguments, the WorkRequest and a tuple with the exception
details as returned by sys.exc_info(). The default implementation
of this callback just prints the exception info via
traceback.print_exception. If you want no exception handler
callback, just pass in None.
requestID, if given, must be hashable since it is used by
ThreadPool object to store the results of that work request in a
dictionary. It defaults to the return value of id(self).
