Hoss has worked on a new FieldCache implementation that should address 
this if finished and used with the new reopen. I have been meaning to 
look at it in greater detail myself, but havn't gotten at it. It sounds 
as if he has been a bit too busy to be be able to work on it himself. It 
would only require the reloading of the FieldCache for the 
SegmentReaders that have changed I each SegmentReader would 
have its own FieldCache...
