    In the current implementation, run_clean waits 5 seconds after running
    the commands before deleting files in rm_list. This should really be replaced
    with a more deterministic way of doing things. Ideally, the remove command should
    actually be part of the command list.

    Choose a remote host on which to execute a program.
    Currently, this is dumb function whose sole task
    is to rotate a list of hosts in $BIRCH/.BIRCHrhosts
    so that no one host always gets jobs. It should be
    replaced with a more sophisticated function that finds hosts
    that the user has permissions to execute programs on.
