If buffer don't get back to the pool in GstV4l2BufferPool I would not 
worry to much since the GstV4L2Allocator already have this pooling 
behaviour Sebastian mention. I also did myself some test to try and 
measure the performance when buffer are being discarded and 
re-allocatate. I could not get any significant difference. The fact is 
that for V4L2 case, re-allocation does not require any OS call, since 
everything is pre-allocated.
