Cool, that indeed solved it! It also helps significantly when data
stores *are* being used; that still takes about 2x the time, but
that's much less than before. Now I'm wondering if we can get that
back down to normal, too ...

One question about Broker's endpoint::advance_time(): that's locking
on each call when in pcap mode, i.e., once per packet. Could we limit
that to cases where something actually needs to be done? Quick idea:
use an atomic<> for current_time plus another atomic<> counter
tracking if there are any pending message. And go into the locked case
only if the latter is non-zero?

Yeah, sounds like it.
