[Distutils] distlib.mount API design (was: wheels on sys.path clarification (reboot))

FWIW, Windows (by default) has a regular maintenance task that will clean up old files in the TEMP directory. I think the default settings will delete files older than 30 days and more aggressively if disk space is running low.
I'd say pick a consistent/static subfolder ('wheel_mount_35_amd64' or something), autogenerate whatever is needed within there, and leave it behind. Users who are concerned can rm -rf whenever they like and everyone else can let the OS handle it.

OK, I think I get the idea now.
I'm still not comfortable with the temp directory clutter that
unpacking leaves (in particular on Windows where deletion isn't even
possible in an atexit routine) but I'll survive.
I *would* like to see the various technical issues and implications in
the API documentation, though. The implications and limitations, and
in particular the manual cache management requirements, need to be
made explicit. (I thought I'd seen docs somewhere, but they definitely
aren't in the API reference for the distlib.wheel module).
