(Yes, I think it's a pretty recent addition.)

Running a tcpdump in parallel is certainly a good thing if you have
the resources for that.

You can use the mechanisms in rotate-logs.bro to rotate the trace
file with all the other logs by adding it to the aux_files set.
(When Bro rotates the files in aux_files, it will automagically do
the right pcap magic for the trace file.)
