Yes I saw your patch, I have not had a chance to try it myself.
I did wonder whether the CPU load of timers.SetEvents could potentially
cause buffering problems on low end machines. Some of the kernel
filesystem handling is performed by asynchronous kernel threads with 
non-realtime priority (e.g. kblockd, journald etc). If VDR is consuming 
a lot of CPU in a realtime thread then this may adversely effect the 
kernel filesystem performance.
