That makes it easy, but ... If the traffic is high, so there is a definite risk that one or more (or many!) tasks may be queued in line for access to the resource, and the resource is a large structure, you may be preventing access to far more than you need to. Maybe others could safely access most of the structure when you are working on another part of it.

Compare it to locking in database systems: The oldest systems locked the entire table, no other transaction could affect any part of it. A banking system with twelve tellers was as slow as one with a single teller, because they all had to wait for the table to be released. The next development step was to lock individual tuples, so as long as the tellers were referring to different accounts, they could proceed.

One main justification for B-link trees (over other B-tree-variants) is that even when a block is split, you need only lock a single block at a time; other threads may freely access all other blocks in parallel.

If you have had no protection until now, there probably isn't that much congestion, and this is not too much of a concern. Yet, as a general rule: It is a good idea to lock only the data that you really are using!
