That seems like a waste of time, such things has been tired before, see
 http://bugs.winehq.org/show_bug.cgi?id=13687
for instance.

The main problem remains the same: tmo=0 isn't handled by Wine like
Windows < Vista does. Any app that relies on the old convention will experience
the 100% CPU or similar. If you really want to help, you should try
my patch on all those 100% CPU bugs in bugzilla and see if that helps.
