The flock implementation in Cygwin 1.5.25 is not very sophisticated
and uses direct calls to the Windows mandatory file locking calls.

The next major release Cygwin 1.7 has a completely new implementation
of file locking (fcntl, flock, lockf) providing advisory file locking.
If you could give it a try, I'd be glad to have a tester for this
code.  Please start here:
