It does seem to me that running it with a socket in $TMPDIR instead of the
current directory would solve the problem, though. Is there no env var
for this? Also during regular operation it looks like this would be not
insane to do if it invokes temporary daemons.

The current directory design is due to the following:

* /build is a separate persistent partition.
* /build/$pkg-$ver-$arch-$random is the base dir to host the source files and
  the unpacked source
* /build/$pkg-$ver-$arch-$random/$pkg-$ver is the result of the dpkg unpack.

Hence you can just remove /build/$pkg-$ver-$arch-$random and be guaranteed
to have no remainder on disk.

Kind regards
