Closing a storage engine snapshot via abandonSnapshot() and WriteUnitOfWork::commit() invalidates the CollectionCatalog snapshot held by callers. There are no preventative measures to ensure that callers do not continue using a potentially invalid catalog snapshot, and this is dangerous.
This causes memory errors and segfaults like this one: SERVER-81331.
This is also likely a problem just for Lock-free-reads operations
