High CPU load by http.so 1

Periodically, http.so processes started by Ktorrent begin to load CPU intensively. There are multiple such processes running, so the total effect is 20-40% CPU load, according to KSysGuard. This period of high CPU usage lasts for about 20-30 seconds, then the CPU load goes back to normal. These high CPU usage periods happen repeatedly at various intervals, I've seen anywhere from about a minute and around 5 minutes. I suspect, the intervals may have to do with how often Ktorrent contacts the torrent trackers.

I've attached a couple screenshots showing high CPU usage.
