As has been pointed out to me, this has been in 1.6 for a while. Sorry;
I thought I checked, but I was looking at the 'git log' for an older
version.

Same thing, though. With 8462 we retry on VNOSERVICE errors, but the
CreateFile operation is not idempotent, so we can't retry it. We
probably should retry CreateFile operations, and swallow an EEXIST error
if it doesn't matter (file was created without O_EXCL). And/or we really
shouldn't let VNOSERVICE propagate to userspace.

"About a minute" I think is enough for this.
