Yes, we'd need to write an extension or depend on ctypes to do this for
win32 if win32all can't do it. Twisted is not "pure python", but it
will work without any C extension modules.

Well if it's not available, it won't work.. perhaps we'd have to divide
it up into multiple interfaces, and have some sort of gestalt mechanism
where you can ask if the reactor can provide the service on the
particular platform it's currently running on.
