FYI, my takeaway is that you can't run parallel 'git pull' operations on
different branches checked out of the same tree, at least as setup from
instructions on our wiki. Such parallel operations generate messages
indicating someone else is working on the tree, but I now realize those
are _warnings_ and this behavior should be avoided. Normally it works
fine, but for a big commit, it can move a changeset from one branch to
another, with disastrous consequences.
Yes, I should have checked more, but I often do a pull before a push as
another check, so that can mess it up too. Basically, if your tools are
being used improperly, checking can make things worse too.
