Isn't the actually *right* thing to do to fix twisted #2234 (Select  
default reactor based on platform and available libraries)?

Since tests currently pass on cygwin (and Windows and some Linuxes),  
I'm satisfied with the current behavior.  If you, or Brian, want  
different behavior, perhaps you could help me understand exactly what  
you want by adding a test that fails.  :-)

I just assigned #530 to you.  :-)

Ideally I would want the buildbot to assert that it is really  
importing and testing the source code that it is supposed to be.   
Could we add to the buildbot script to import the allmydata package  
and inspect its __file__ attribute and fail the buildstep if it isn't  
the path we were expecting?

Thanks!
