No, it's not. And the problem happens with *every* bind mount,
except for the parent of the build directory, which I believe
--use-pdebuild-internal bindmounts.

I think I have found the root of the problem. I bind mount
/tmp/pbuilder-shared. If I build with --internal from
/tmp/postfix-2.3.2, pdebuild will bind-mount /tmp as the parent over
the /tmp holding the other bind-mounts, so they won't be accessible
until after /tmp is umounted again.

Solution? Maybe try to bind mount the user's bindmounts *after*
bind-mounting the parent when --internal is used?
