Memory leaks?

Is it just me, or is there some huge memory leak going down atm? My server has been online for a day now, and it's just eating memory like nobodies business. I haven't done a manual re-scan, but it will have done one automatically, but the memory leak appears to be primarily related to what you stream... In my case, it seems to leak worst when streaming video content...

Any suggestions on how this might be prevented? RAM is a somewhat limited resource on the machine this is running on, and I may be forced to switch to another streamer if I can't at least slow this down.
