Yes, I think I never did send a PR on that, I think because (at the time,
at least a year ago now) I saw messages that seemed to indicate that it was
a fairly well known problem. Will do. If my setup is still in place
(which it might be) I might be able to re-discover which register it was
that was being lost (g3 or something I vaguelly remember). The effects
weren't at all subtle...

Perhaps, if I can work out some automated detection system. Unfortunately,
without hanging the process doing the check it isn't easy to get something
reliable. I think I'd just prefer to set up a controlled experiment,
make a mount with the right options, turn off the server (which will be
a server for just this one client for the test, so this will be harmless)
and then watch and see what happens...
