/**
* Determine if the editor should hold a read lock on the object while
* applying a transaction.
*
* If the editor does not hold a lock, two editors may read an object at the
* same time, then apply their changes without any synchronization. For most
* transactions, this does not matter much. However, it is important for some
* transactions. For example, if an object has a transaction count on it, both
* editors may read the object with `count = 23`, then independently update it
* and save the object with `count = 24` twice. This will produce the wrong
* state: the object really has 25 transactions, but the count is only 24.
*
* Generally, transactions fall into one of four buckets:
*
* - Append operations: Actions like adding a comment to an object purely
* add information to its state, and do not depend on the current object
* state in any way. These transactions never need to hold locks.
* - Overwrite operations: Actions like changing the title or description
* of an object replace the current value with a new value, so the end
* state is consistent without a lock. We currently do not lock these
* transactions, although we may in the future.
* - Edge operations: Edge and subscription operations have internal
* synchronization which limits the damage race conditions can cause.
* We do not currently lock these transactions, although we may in the
* future.
* - Update operations: Actions like incrementing a count on an object.
* These operations generally should use locks, unless it is not
* important that the state remain consistent in the presence of races.
*
* @param PhabricatorLiskDAO Object being updated.
* @param PhabricatorApplicationTransaction Transaction being applied.
