Just to double-check: does the abort happen

a) immediately
b) relatively soon after start
c) some time after start, probably late

I think it is b). Reason for question: I would eventually like to add some instrumentation, but that makes sense only if we do not need to wade through several GB of debug log...

The free-running doesn't survive more than a couple of hours; I still
haven't tried a free-running with -dn appended; let me know if you'd
prefer for me to try starting the daemon now, or if it's better if
I wait for some more commits.

As for testing, in as much as I understand, to reproduce the problem we
are going after there would be a need for a load-test harness, and some
patience, since, in my case, the "writer" server does work without any
problem, and the crashes do happen on one of my loaded mail gateways,
which get some thousand messages per hour, and do antispam and antivirus
work, with sendmail, mailscanner and clamav each spewing a lot of messages
to filter and dispose of.

See you later, yours
