Yes.

IOCP is not a replacement for WSAPoll (or select).  Among other things it is not possible to use the current ssl module with IOCP (although Twisted manages to use IOCP with PyOpenSSL).

Tulip should have IOCP support, so presumable when tulip is merged some support for IOCP will also be available in python.  But I am not convinced that the select module is the proper home.
