That won't work. The Windows select function is only implemented for
sockets. To implement a POSIX select function which allows to select on
any descriptor one needs to implement it specificially for each known,
resp. useful file type. Naturally this won't work with a generic
Windows handle since Cygein doesn't know what it represents. So Cygwin
is unable to provide a matching select function.
