Memory leaks in c/pthread libraries

[Brian Marcotte]

Since upgrading to NetBSD-10, we've seen memory leaks in several
daemons which use libpthread:

    gpg-agent
    opendmarc
    dkimpy_milter (python3)
    syslog-ng (in some cases)
    mysqld
    mariadbd

In most cases, the daemons leak as they are used, but running this
will show the leak just sitting there:

  gpg-agent --daemon

I opened PR#57831 on this issue back in January.

Has anyone noticed this?

Thanks.
