backport tim_one's checkin of
    revision 1.21 of test_mmap.py

SF bug 544733:  Cygwin test_mmap fix for Python 2.2.1
Close a file before trying to unlink it, and apparently Cygwin needs
writes to an mmap'ed file to get flushed before they're visible.

Bugfix candidate, but I think only for the 2.2 line (it's testing
features that I think were new in 2.2).
