Currently looms conflate the pull location for the whole loom (if you
were collaborating with multiple people on the same loom and wanted to
update) with the pull location for the bottom thread (if you want
to pull in the latest code.)
In addition there is no way to specify locations for other threads,
so you could e.g. pull the upstream thread, up thread and then merge
a branch of that upstream, then up-thread to work on your modifications
on top of the combination.
This has two problems:
* Ubuntu developers have to remember locations of everything so they
can type them in to e.g. pull upstream, or we add new infrastructure
on top to remember for them.
* The pulls can't be automated for daily builds, unless we again add
new infrastructure on top.
