Summary: select behavior undefined for empty lists

Initial Comment:
<nit-picking>

The manual for select.select() says:

"Empty lists are allowed, but acceptance of three empty

lists is platform-dependent. (It is known to work on

Unix but not on Windows.)"



I believe that one of the advantages of high-level

languages is that they (are supposed to) shield the

programmer from platform specifics where possible.

Surely it can't be a problem for the select() wrapper

to have defined, platform-independent behaviour for

three empty lists?

Both asyncore and Twisted have code to deal with this

Windows issue, so most people never encounter it. A fix

(doing a sleep in the C code, essentially) would be nice,

but I suspect no one will bother unless you attach a patch.
