"Mutual exclusion, or mutex, locks were introduced in V3R1M0. A mutex lock
is a high-speed locking primitive that is an order of magnitude faster than
a space location lock."

Locks are a function of the task dispatching element of the machine and do
not rely on any processor primitives.  Correct?

Any knowledge of why a mutex is "an order of magnitude" faster than a space
lock?
