Thank you!, that was it. It wasn't my bug however :[, as the CreateFile
is still failing, but the alloc_sd failures are gone (different sd's are
used).

*sigh*. Something is tromping on a static class member and invalidating
the sd. Are sd's ever corrupted by system calls, or can one reuse an sd
indefinately?
