Transmission

Well, overnight test run reveals more probs, as number of peers grow - so does cpu usage, I've found T in the morning constantly using 20-25%.

Update on the status.
So, testing with svn r7516 - T behaves much better. Now it's mostly within 2-4%, sometimes going up to 7-10%. (Seeding 25 torrents, 80kb total upload limit, turning off global limits gives 2-4%, as it should)
I'll leave it for a night and update if something changes.

Upd ...

I can confirm that. I've also found out, that turning off bandwidth limits cures this (at least using r7514 nightly).
Hope this helps devs to pin this bug (shaper code i guess) down.
