codebrowse leaking memory in spikes (vs gradual)

[Steve McInerney]

Just had to restart codebrowse as it was eating swap.
* on guava is a full core file of same, from just before the restart: ~/core.16153 3.5Gb uncompressed
* the process wasn't that old:
Was started: Wed Jul 21 00:04:54 2010
Restarted at: Fri Jul 23 07:37:24 UTC 2010
* doing a quick look over our process logs a couple of 'spikes' in memory usage standout:
RSS usage happily sits under 500Mb till just after 2010-07-21:13:51:26
where over a few minutes to 2010-07-21:13:56:05 it climbs to ~ 1Gb RSS.
couple of twitches up/down and has settled down to ~ 1.2 Gb by 2010-07-21:14:18:18

Shortly after 2010-07-21:16:55:19 we jump to ~ 1.5Gb RSS, a few mins later peak at 1.8Gb, and shortly thereafter, hold steady at 1.5Gb.

The biggie was next.
Shortly after: 2010-07-21:22:51:20 we jumped from 1.5Gb
2010-07-21:22:52:21 ==> 1.8Gb
2010-07-21:22:53:26 ==> 2.8Gb
2010-07-21:22:54:24 ==> 3Gb

Where it stayed, fairly constant, until gcore'd and restarted.

I'm pretty sure this is a duplicate of bug 518689, no?
