improve data migration performance
possible alternative: use a global MVar for whether a migration is in progress (finer grained might be possible as well), thus serialising the migrations.
problem: possible message loss when not all subscriptions are transferred yet and new incoming messages are only forwarded to already migrated subscriptions, but won't reach yet-to-be-migrated ones.
counter measure: stop semantics, during migration new messages are rejected and need to be queued for retry at the senders.
