 the sumstats framework might cause a memory leak in the Bro core.

 On landfill, I get the following pprof output when running a pretty
 minimal
 script (attached) using the topic/seth/metrics-merge branch.

 You need to run the script on a trace with connections - I used the very
 short
 ftp-ipv4.trace trace from testing. The leak seems to become worse over
 time.

 I am not entirely sure if it really is a leak or just some… artifact of
 the google
 perf tools. But on a first glance, it might be one.
