According to this thread, perl opens the file for reading in
place, unlinks it (the unlink is queued by cygwin), opens a same
name file for writing, gets a Windows error message that file
exists, and so can't write and the operation is canceled. The
unlink is not canceled however, and so the file is deleted.
