Well, the issue is we are moving to an Arista switch feeding a 64 core,
40 Gbe sensor, so I really need an indexed packet capture process that
is either multi-threaded (bro and moloch are not); or a way to
post-process packets from suricata, which is my preferred solution.

I just realized a great solution would be to use the approach barnyard
does and have the indexer use a spool directory and asynchronously index
the files as they are written.  This fixes the issue with the buffering
and indexing delays.

I'll look if there are any FPC solutions out there that already do this,
but I don't think there are.
