Filter sinks have this in the beginning of their pop callbacks:
/* Hmm, process any rewind request that might be queued up */
There should never be any rewind requests pending when the pop callback is called, so this is a useless call (pretty harmless, though). Fixing this should be trivial (just remove the calls), but I think there should be some testing done before pushing the fix, which is why I'm filing this bug instead of just fixing it.
