We could remove it after ghc 6.12. Makes the init test fail.

Applied, thanks. (I have added a comment with a link to the GHC ticket. I am not
sure this is yet fixed in 6.12, even. We can watch the ticket anyway.)

I'd be careful here.  There are various things that can give rise to 
"permission denied" errors on Windows, some of which we understand and 
some of which we don't.  That GHC ticket (#2924) is an issue we don't 
currently understand, but it may well be that the issue you have is 
something that you can fix in darcs, e.g. holding an open Handle to 
something in the directory.

Another reason to be cautious is that the workaround (performGC) looks 
very expensive.  And indeed if that is a workaround, then it indicates 
that perhaps you have a finalizer waiting to run.  Or perhaps it's just 
the case that waiting a little while avoids the problem: in which case 
doing exactly that (threadDelay) might be a better workaround.
