I actually meant the output of cacls for the file on your local disk :)

Anyway, the strace output shows that a sharing violation occurs.  There's
another process accessing the file, and that other process opened the
file with one of the sharing flags, probably FILE_SHARE_DELETE, not set.

I assume that's your virus scanner.  In theory I would shrug that away
as a BLODA problem, but I have one or two ideas how to fix this problem.
It might help in a couple of cases where BLODAs are involved.

May I send you a link to a test Cygwin DLL via PM?
