Comment 2 for bug 151580

I don't think this is correct, at least without *very* significant care in umountfs. If FUSE processes aren't killed by sendsigs, then umountfs has to take extra care to umount filesystems in the right order. Its current code that sorts by decreasing length of mountpoint name will not be adequate for this, because for example a FUSE program in /usr might be used to implement a filesystem mounted on /a.

This is far too delicate to be appropriate for gutsy.
