Hi,

Sorry for not answering sooner, I was distracted by work

So generally, my patch is basically just a "hack" to get it work.

While it does work mostly, it is not the best and correct implementation,
and Alexandre wants a correct implementation of Condition Variables.

I don't have the time to do it right currently.

This might be easier to get in as above, but it should be seperated
out and likely needs a testcase.

Perhaps the other gurus can take it ;)

No worries, even feedback and hacky patches help to show where
Wine can go :)
