A win32event based implementation of the Twisted main loop.
This requires pywin32 (formerly win32all) or ActivePython to be 
installed.
To install the event loop (and you should do this before any 
connections, listeners or connectors are added):
   from twisted.internet import win32eventreactor
   win32eventreactor.install()
Maintainer: Itamar Shtull-Trauring
LIMITATIONS:
  - 
    WaitForMultipleObjects and thus the event loop can only handle 64 
    objects.
  
- 
    Process running has some problems (see Process docstring).
  
TODO:
  - 
    Event loop handling of writes is *very* problematic (this is causing
    failed tests). Switch to doing it the correct way, whatever that means 
    (see below).
  
- 
    Replace icky socket loopback waker with event based waker (use 
    dummyEvent object)
  
- 
    Switch everyone to using Free Software so we don't have to deal with
    proprietary APIs.
  
ALTERNATIVE SOLUTIONS:
  - 
    IIRC, sockets can only be registered once. So we switch to a 
    structure like the poll() reactor, thus allowing us to deal with write 
    events in a decent fashion. This should allow us to pass tests, but 
    we're still limited to 64 events.
  
Or:
  - 
    Instead of doing a reactor, we make this an addon to the select 
    reactor. The WFMO event loop runs in a separate thread. This means no 
    need to maintain separate code for networking, 64 event limit doesn't 
    apply to sockets, we can run processes and other win32 stuff in default
    event loop. The only problem is that we're stuck with the icky socket 
    based waker. Another benefit is that this could be extended to support 
    >64 events in a simpler manner than the previous solution.
  
The 2nd solution is probably what will get implemented.
