large flash videos stop playback when reaching boxee file system limit

480p at 40min. 1080p at 6 minutes.

example scenario:
* watch the HD flash videos 720 or 1080 from youtube
* for example, watch the youtube movie "home"
the playback continues until tmp folder reach its limit.
the video continues to play properly.
* continue to play and after few minutes the video pauses.
* hd videos stop to play at 10-15 minutes
* "home" video freezes at around 18 minutes
* boxee tmp directory is full with 300mb

Filesystem Size Used Available Use% Mounted on
tmpfs 300.0M 300.0M 0 100% /tmp

version 1.0.1.16260 improves the behaviour and the video "Home" reach file system limit only at 45 minutes.

workaround:
pausing the video and small skip backward clears the tmp folder and helps the video to proceed playing.
