After updating gnupg to 2.5.17 in pkgsrc I ran the self tests and noticed them hanging. The symptom is:
```
Making check in migrations

Testing a clean migration ...
```
and then nothing happens.
There are three gnupg related processes I found:

In case it matters, this is on NetBSD 11.99.5/x86_64.
I also see hangs when running gpgme self tests or the notmuch configure script.
