Then he/she may expect that the file will not be suddenly unlinked
while he/she is still reading. The documentation for System.IO says
that the implementation should provide single writer - multiple
readers locking. When that is the case then copyFile should fail if
the target fail is open for reading or writing from someone including
the OS. The Unix implementation provides only local locking but the
Windows implementation provides system wide locking.
