The problem is that when this happens, the system becomes unusable. Videos stop playing, switching between windows takes more and more time, mail client is painfully slow, etc. If I leave the system alone when this starts happening the clock eventually consumes all CPU, the system freezes, or it crashes. Since the last 2 require a full fsck to recover from I tend to power down first. :) BTW, something interesting happened the other day. I was having this problem over and over with the same hulu video, so I finally switched to windows in order to just finish watching it. After about 5 minutes watching the same show in windows the video started to stall just like it had in freebsd, but after about 5 seconds of that it "caught up" with itself, and I was able to watch the last 20 or so minutes without any problems.
