Yes. The article I mentioned talks about row "locking" in the sense of
using a transaction between the read and the write so that no other
writes can happen between the initial read and write. And it points out
that php locks the session file for each request. Locking only when
needed can speed up applications, especially if they are AJAX heavy.
