it wouldn't surprise me if there are indeed processes still hanging
around due to modern GnuPG's multi-process model (with dirmngr and
gpg-agent getting launched as-needed).

If you're doing the build on a modern linux system, and you haven't
explicitly disabled the GnuPG's inotify support, and the test suite
deletes any temporary GNUPGHOME homedirs, the subprocesses should notice
the deletion and terminate promptly.  This might depend on relatively
recent versions of "modern" GnuPG, though (debian's currently shipping
2.1.17, fwiw).
