Well, not all handles are created equal anyway, but the point I was making
that PyHANDLE object automatically close the handle when it dies - like a
file object.  So the handles will be closed even if you do not explicitely
close them.

My comment wasnt intended to throw light on the specific problem - just
point out an advantage that PyHANDLE objects have.  OTOH, I am wildly
guessing that using CreateFile could solve the problem - not due to the
"auto-close" behaviour, but simply because they remove the indirection.  I
have no basis for believing it will solve the problem, just a guess!
