For some reason I never looked at the actual value of this; I thought
ENOBUFS was some low-numbered errno for some reason. But it appears to
be 105, which is VNOSERVICE, which means this is probably due to
Speaking to you in the context of 1.6 maintenance: this isn't really new
(though this specific manifestation might be, I'm not sure). Gerrit 8462
would help with it, and could possibly go into 1.6.6 if we want to do
something about it. Actually fixing it was discussed in 8464; I just
need to get around to actually implementing it sometime (none of the
submitted patches in there are correct; a different solution is
discussed somewhere in there).

I assume this was hanging for a little while before erroring out, yes?
