Seems that comment was wrong. Now when stream_Read is fixed, I did a little
testing using a 1 Gig file in memory dumping do /dev/null and the average
results for 10 attempts are:

demuxdump with stream_Read: 1.79 s
demuxdump with stream_Peek: 1.83 s

stream_Peek calls block_ChainGather() at the end, which is more CPU expensive
than a simple memcopy.

We should probably revert this and remove the misleading comment.

   With kind regards,

        M.
