I do not think you hit a uid_wrapper bug but that your machine triggers a 
Samba bug!

I completely rewrote uid_wrapper so that it works correctly. The old code, 
before the preloadable uid_wrapper was added, was hackish and several things 
were completely wrong.

The current uid_wrapper code is well tested, we have 78% code coverage.

I would say that a uid_wrapper bug is unlikely. As it works just fine in 
master on my box, I would say it is a race condition in Samba!
