Earwin Burrfoot commented on LUCENE-1645:
-----------------------------------------
Either that. Or having boolean readerShared[] as a property of MSR, and check
it on each modification attempt -> lazy clone().
*rant on*
Or make readers immutable :) I already have a patch that removes norm updates,
lazy loading and synchronization. Then we only need to do deletes in
IndexWriter without resorting to its reader pool.
By the way, do we need public IR cloneability? Not for Lucene internals, but
for actual users? That really looks like one more feature that can be safely
removed.
