Where is it used so much?  In the stdlib, grepping for WindowsError
recursively in Lib in 2.4 turns up only one module raising it
(subprocess) and only two modules with a total of three places of
catching it (ntpath once, urllib twice).  In Module, there are no
hits.

I can compromise to this if others prefer this alternative.  Anybody
else have an opinion?
