Hi Hans,
Please don't write a FAM dependent implementation. This introduces an unnecessary dependency in Wine, and as you mentioned a polling solution to this problem is wasteful or CPU time.
I submitted a patch a couple of months ago that implements a kernel based solution (using F_NOTIFY) to the problem, which IMO is much nicer.
My patch is at:

We sometimes doubt will be able to support correctly FindFirstChangeNotification under Wine without proper kernel support, which doesn't exist yet... so it'd be a hard task
You know, a couple of weeks ago I looked at the possibilities of a FAM based implementation, as suggested in bugrequest #588:
http://bugs.winehq.org/show_bug.cgi?id=588
There are other solutions (dnotify, fmon on FreeBSD), but FAM is
available now on RedHat and Mandrake distributions, which gives it an avantage. Furthermore, FAM will fall back to a polling
strategy when kernel level support is absent. I think it's
the best candidate.
