I think they should be OK. The daemons run on the loopback interface, so
there is hopefully not a security implication. If multiple buildfarms
are sharing the same loopback space (e.g., running in separate
directories on the same machine), the "auto" setting should degrade
gracefully. One daemon will "win" the setup, and the tests will run, and
on the other, they will be skipped.

Agreed, but I think the only way to know the size of those fallouts is
to try it and see who complains.  I would not normally be so cavalier
with git itself, but I think for the test infrastructure, we have a
small, tech-savvy audience that can help us iterate on it without too
much pain.
