However, using the lock-modify-unlock method for this scenario causes (in my opinion) even MORE pain for poor developer B. Instead of simply having to run a test once more, dev B will actually have to sit around and wait to START any changes to the common file until after dev A has FINISHED testing and committing all changes for A's ENTIRE TASK, finally unlocking the file that dev B needs. I hardly consider this an advantage.

That is assuming that you enforce a strict exclusive lock on the files,
which we typically don't, unless the file is of the nature that really
needs it (point for a different discussion). But at the very least,
both developers know that someone else is making changes to the same
file, and can take appropriate action PRIOR to having the issues.
