Sorry for the delay, I now have a prototype patch that you could try if you
want (feedback would be very appreciated). Unfortunately, it is completely
untested:

   http://data.plan9.de/winselect.diff

The basic idea is pretty simple: whenever the handle changes, we first tell
the backend to remove all events (backend_modify (.., 0)) - the existing code
should then re-arm the backend with the desired watchers.

If that works then this or a similar patch will be part of the next release.

Thanks for analyzing the problem :)
