I'm not sure I understand what you mean.
FD passing is supported on Unix with sendmsg/SCM_RIGHTS, and on
Windows using whatever Windows uses for that purpose (see
http://hg.python.org/cpython/file/2b47f0146639/Lib/multiprocessing/reduction.py#l63).
If we remove the check for Windows, an ImportError will be raised
systematically, unless you suggest that Windows does support
sendmsg/SCM_RIGHTS (I somehow doubt Windows supports Unix domain
sockets, but I don't know Windows at all).
