I'll hold onto it for a bit, but there's no need for a close review
process here.  The code works fine on POSIXish hosts and we've done a
quick scan for plausible failures on Windows hosts and have come up
dry.  Any problems that come up on Windows will likely be either
easy-to-fix compilation issues, or further simplifications of the code
that will not fix bugs.
