_cpl is a problem.  I noticed this because performance
went to hell.  John, have you thought about this before?
Can/should _cpl be a per-processor variable?

        MPLOCKED incl _cnt+V_SYSCALL
        ECPL_LOCK
#ifdef CPL_AND_CML
        movl    $SWI_AST_MASK,_cml
#else
        movl    $SWI_AST_MASK,_cpl
#endif
        ECPL_UNLOCK
        call    _syscall
