Tested with a fresh build of TSVN. The crashes are gone now, at least I
didn't get one during my tests.

Yes, there's a massive memory leak somewhere. A checkout of the TSVN
trunk used up more than 2GB or RAM.
I had to stop a test checkout of the KDE trunk once it used up more than
3.5 GB and basically slowed down my whole system.

To compare, I switched to neon and the memory use didn't grow over about
60MB.

All this tested on Win7 x64.
