sorry for the disturbance...)

Well, this naming issue is all about overloading... To circumvent the
overloading problem, we can also use some other name pairs like
`start'/`stop' or `begin'/`end' (Gentoo and LaTeX user here ;). But
that introduces another problem: more names to remember.

So this is somewhat a dilemma. Different context and developers might
lead to different decisions; I personally would rather like to support
overloading the `run'/`finish' name pair, for the similar reason for
Unix's choice of the `x' permission bit to represent both "executable"
for files and "enter-able" for directories: they are loosely correlated
concepts in orthogonal "subspaces".

The same reason explains why I think `up'/`down' are worse names:
because `run'/`finish' (in longruns) and `up'/`down' (in longruns) seem
much less correlated than `up'/`down' (in longruns) and `up'/`down' (in
oneshots currently).
