Hmm, I'm still seeing much larger runtimes on that M57 trace using our
test configuration, even with yesterday's change:

; Master, pre-Broker
# zcat 2009-M57-day11-18.trace.gz | time bro -r - tests/m57-long.bro
73.72user 7.90system 1:06.53elapsed 122%CPU (0avgtext+0avgdata 199092maxresident)

; Current master
# zcat 2009-M57-day11-18.trace.gz | time bro -r - tests/m57-long.bro
2191.59user 1606.69system 12:39.92elapsed 499%CPU (0avgtext+0avgdata 228400maxresident)

Bro must still be blocking somewhere when reading from trace files.
