_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
