Ops, already in master branch?
Ok, I found out that the custom fstat function was incomplete, so I 
completed it. However, since you've already pushed it to your main 
branch, I've added it as a separate commit to the 4msysgit.git 
'teststat' branch. It might also explain some of the testfailures we 
were seeing, but I haven't finished the test run yet. (So, consider 
the patch something to play with, and don't commit it to your 'master' 
branch yet! ;-)

Ok, I can give it a performance test, but I tend to agree with David 
Kastrup there. It would be better if we rather fix the places where we 
check with the local timestamp instead; depending of course on how 
many places we actually do this.
We'll see how much the timezone conversion in the custom stat 
functions actually hurt us performance wise.
