I've been using the stable releases, so master could be a big jump, but
sure; I'll try it out.

I double-checked using VmRSS now; it is showing pretty much the same
picture. (Checking on my laptop, with the same tracker version 0.8.6)
VmRSS rises by about 1MB/s until tracker-store starts swapping heavily;
I killed it on my laptop once VmRSS hit 2GB (at about 50% through
indexing a rather smaller /home).

<after installing and testing tracker git master...>

Looks like the development branch fixes the problems I was having.
tracker-store's memory usage is insignificant (~14MB RSS, growing by
100k every 5 minutes or so), CPU usage is lower (previously
tracker-store was pegging a CPU at 100%), and indexing speed is up.

I'll let it run until completion to see if anything else pops up, but
it's looking good so far.

Are there plans to backport these fixes onto the 0.8 branch, or should I
attempt to pressure my distro into packaging the 0.9 branch?
