Perform the given task.

As an interface, this method makes no specific claims about concurrent
execution.  An L{IWorker}'s C{do} implementation may defer execution
for later on the same thread, immediately on a different thread, or
some combination of the two.  It is valid for a C{do} method to
schedule C{task} in such a way that it may never be executed.

It is important for some implementations to provide specific properties
with respect to where C{task} is executed, of course, and client code
may rely on a more specific implementation of C{do} than L{IWorker}.

@param task: a task to call in a thread or other concurrent context.
@type task: 0-argument callable

@raise AlreadyQuit: if C{quit} has been called.
