Description

see https://github.com/10gen/mongo/blob/1301f35e5dcb08e55d79c7213cc48165c2b49156/src/mongo/db/repl/tenant_migration_recipient_service.cpp#L1834

although this is technically safe right now (nothing concurrently accesses the buffer), _donorOplogBuffer is marked with (M) signifying that it must be accessed while holding a mutex. we should clean this up and make this explicit.

also investigate other properties where this might be the case.
