Semophores can be efficiently implemented on "old" x86 by means of
'LOCK ADD mem, reg'. It is possible due to arithmetic flags generated
by ADD instructiion. As far as semaphores goes 'LOCK XADD' adds little
or nothing to efficiency over 'LOCK ADD'. XADD is just easier to use as
an intrinsic from C or similar languages.
