In a more perfect world, the dispatcher would get the CPU to programs that do not hog it and that do i/o on an expedited basis. I remember amazing operators who were copying tape with the difference if I made the job APRIOR, which meant real time. The drive went from "bup bup bup" to "ZZZZZZZZ", and nobody suffered, because it was i/o bound. Programs like that need to take their 1% off the top, which is no harm to the 99%, especially when there is still idle time. Writing dispatches is a big deal some places. One sysadmin refused to kill a looping pg for me, because he said their very custom dispatcher ensured that the CPU it took was off the bottom, so they had a policy to just wait for the periodic reboot.

NAME
bup-fuse - mount a bup repository as a filesystem SYNOPSIS
bup fuse [-d] [-f] [-o] <mountpoint> DESCRIPTION
bup fuse opens a bup repository and exports it as a fuse(7) userspace filesystem. This feature is only available on systems (such as Linux) which support FUSE. WARNING: bup fuse is still experimental and does not enforce any file permissions! All files will be readable by all users. When you're done accessing the mounted fuse filesystem, you should unmount it with umount(8). OPTIONS
-d, --debug run in the foreground and print FUSE debug information for each request. -f, --foreground run in the foreground and exit only when the filesystem is unmounted. -o, --allow-other permit other users to access the filesystem. Necessary for exporting the filesystem via Samba, for example. EXAMPLE
rm -rf /tmp/buptest mkdir /tmp/buptest sudo bup fuse -d /tmp/buptest ls /tmp/buptest/*/latest ... umount /tmp/buptest SEE ALSO
fuse(7), fusermount(1), bup-ls(1), bup-ftp(1), bup-restore(1), bup-web(1) BUP
Part of the bup(1) suite. AUTHORS
