Memory leak

[TRPB]

This seems to be an issue with this plugin. Whenever I'm watching a TVHeadend stream via HTSP the memory usages for buff/cache grows and grows here's me running free over the space of about 1 minute:

Eventually VLC crashes when it runs out of memory. This may be something to do with timeshifting as I have that enabled in TVHeadened, but as that's the only reason to run HTSP instead of HTTP it's unlikely nobody else has encountered this.
