Discussing this on IRC ([1] through [2]), Jeromy and I decided that
we'd really like a way to configure per-command [3] and per-action
timeouts, but until we have that we want to leave the minute limit
here.  We also decided that the use of TODO here instead of the
per-command req.Context().Context was a bug, which I'm fixing with
this commit.
