Then I'm not certain qmail-send actually exited.

Fair enough, that's your choice. Though I would suggest looking at
multilog (from daemontools). I find it very efficient.

I think it's quite likely you're seeing qmail merely retrying messages
it's had to defer because of DNS problems. Are the 96 messages destined
for addresses within the same domain? Or perhaps in domains served by
the same nameservers?

The scenario could have been something like:
1. qmail receives ~90 messages to be sent to domain X.
2. Domain X has dodgy DNS, messages all get deferred.
3. qmail waits a bit, and tries (all) the deferred messages again.
4. Repeat 2 and 3 until DNS problems get sorted.

DNS problems, especially those that manifest themselves as time-outs,
will lengthen how long a qmail-remote runs for each delivery
attempt. When they run for longer more of them are likely to be 
running concurrently.
