> On Windows, a file won't be deleted until every open handle on it is closed.
> So if a file is deleted and immediately recreated with the same filename, the
> creation fails if another process (typically a virus scanner) still has an
> open handle on it. The solution is to create temporary files with unique
> names. I propose to add the following function to {{OperatingSystem.c}} and
> use it for every temp file:
> {noformat}
> char*
> chaz_OS_temp_filename(const char *prefix, const char *ext);
> {noformat}
> It should simply add a number to the filename which is incremented on every
> call to that function.
> (Currently, the effect is that Charmonizer occasionally fails in
> {{chaz_Util_remove_and_verify}}. This kind of verification isn't reliable on
> Windows.)
