Ugh, this is a regression introduced by my patch...
(see [PATCH] qemu: fix monitor socket reconnection)
Eventually we need to add ENOENT to errno checks, not replace EACCES
with ENOENT, I'm not sure why EACCES happens though. Anyone knows that?

Unclear, he's using the prerelease code from monday, not the one
with the EACCES -> ENOENT replacement patch.
One possibility for EACCES could be if the socket creation in qemu was
done with a mode not allowing access and modified in subsequent code,
allowing for a small windows where EACCES would be returned. Someone
should check qemu code.
I think allowing again retry on EACCES should be fine anyway, I don't
see how that could break things, we would just hit a time out in the
worst case where access is never granted.
So my take is to just do the enclosed patch,
Daniel
