FYI: on PL/Proxy we use poll() exclusively and on platforms
that dont have it (win32) we emulate poll() with select():

http://cvs.pgfoundry.org/cgi-bin/cvsweb.cgi/plproxy/plproxy/src/poll_compat.c?rev=1.3&content-type=text/x-cvsweb-markup

End result is efficient and clean #ifdef-less code.

Something to consider.
