> TxnHandler.checkLock() see more comments around "isPartOfDynamicPartitionInsert". If
TxnHandler knew whether it is being called as part of an op running with dynamic partitions,
it could be more efficient. In that case we don't have to write to TXN_COMPONENTS at all during
lock acquisition. Conversely, if not running with DynPart then, we can kill current txn on
lock grant rather than wait until commit time.
> if addDynamicPartitions() also knew about DynPart it could eliminate the Delete from
Txn_components... statement
