-------------------------------

Ok on the above reasoning. Thanks.

On why my name no longer pops up in JIRA, I think its because I got banned because of all
the bad code I've done down through the years! (Not sure!)

> We try switch over to stream scanner if we have read more than a certain number of bytes.
In case of compaction we already have stream based scanners only and but on calling shipped()
we try to again close and reopen the scanners which is unwanted.
