I thought I'd checked this and that killall was working off the output
in ps which was based off argv[0] and was unchanged. Checking again
just now shows that isn't correct.

I guess the question is where to include "bitbake". We're short of
space already for the worker processes for example. Perhaps if we just
included bitbake for the cooker and UI?
