The ability of the kernel and/or the thread library to run many threads which
acquire/release a mutex over a short critical region frequently without
excessive context switches. In other words, if the implementation of
@code{pthread_mutex_lock()} is too anxious to yield CPU, this will hurt
MySQL tremendously. If this issue
is not taken care of, adding extra CPUs will actually make MySQL
slower.
