 hiya michael,

 good point - although the "success" instance was under wine (when it
should not have been successful, according to the exact same test with
the exact same app running under xp).

also note it's file descriptors not file handles, and to emphasise
this, the selectmodule.c in python i had to increase the #define
FD_SETMAX to 2048 in order to cope with the massive number of file
descriptors - both under wine and also native xp in a qemu VM.

funny.  it's always the bumbling-along not knowing what's really going
on that finds the errors.  if you quotes know what you're doing quotes
then you always do things quotes right quotes and the errors are never
encountered....
