-----------------------------------------
bq. Right; I think we should simply clone shared subreaders on reopen.
IFF the subreader being cloned is not readonly!
bq. I think it's too soon to do this.
Hey, let's reverse readonly/writeable reader inheritance?
WriteableSegmentReader extends SegmentReader.
SegmentReader is readonly by behaviour and in code - there are no syncs and
mutator methods throw UOE. WriteableSegmentReader adds a writeability layer
over SegmentReader and all the gory syncs.
bq. I think we do? Eg it enables you to clone a readOnly reader to a read/write
one in order to do deletes/setNorm.
Hey, open a new IR if you want to write. Cloning/reopening an IR while
simultaneously switching readonly flag is a feature that gives user zero new
functionality, absolutely nothing he can't accomplish using a new IR, but makes
reopening/cloning code more complex.
