Jonathan Ellis commented on CASSANDRA-2252:
-------------------------------------------
I see what you mean: you want to allow a Region to "die" if all the buffers it
was responsible for have been overwritten and thus the Region is no longer
needed for flush. In that case, weak references sound reasonable. However,
I'm not sure it would make any difference in practice since we allocate row
keys into the regions, as well.
