These implementations aren't "broken", so much as "limited".

Please feel free to contribute patches which reduce these limitations.

It still doesn't support SSL, though:


and maybe some other features too (I don't have a Windows handy or the 
time required to read the code to check - this really ought to be 

The select reactor is also convenient for testing on Windows, because 
it's the basis of at least one GUI reactor (GTK+) which should also 
support Win32.

Your suggestion for handle buckets in the win32eventreactor is one which 
has been suggested before and sounds good to me.  Nobody has bothered to 
implement it yet :).  However, even in its absence, I don't believe 
we'll be completely dropping win32eventreactor because it is useful for 
integrating with programs that do win32 drawing, even if iocpreactor has 
higher performance and is more scalable.
