> I switched mhttpd to use the new javascript based run start and stop pages.

One initial complaint: the transition.html page doesn't seem to deal well with a frontend program using
a deferred transition.  Specifically, I find with my simulated frontend ([1]), which has a deferred
end-of-run transition, that two problems happen:

i) the page doesn't give any indication that a frontend has a deferred transition; in fact it says that
the frontend immediately has finished the transition.
ii) once the deferred transition has finished, the page doesn't switch to saying that the run has
stopped.  In fact, even if I reload the transition page it still continues to show that the run is
ongoing; the status page, by contrast, shows that the run has stopped.

I separately still think that the transition page should automatically go away after 5 seconds
(assuming that all the transitions were successful).  I think it is annoying that you need to click
back to the status page.
