Marcus Eriksson commented on CASSANDRA-8707:
--------------------------------------------

bq. simplify by not distinguishing between the global and per-descriptor-type state.
bq. eliminate all of the XManager classes.
bq. merge GlobalTidy and TypeTidy

lets try that?

> There are still a few bugs with resource management, especially around SSTableReader
cleanup, esp. when intermixing with compaction. This migration should help. We can simultaneously
"simplify" the logic in SSTableReader to not track the replacement chain, only to take a new
reference to each of the underlying resources.
