-          SMTC pseudo-interrupts between TCs are deferred and queued

           To support multiple TC microthreads acting as "CPUs" within
           a VPE, VPE-wide interrupt mask bits must be specially manipulated
           during interrupt handling. To support legacy drivers and interrupt
           controller management code, SMTC has a "backstop" to track and
           if necessary restore the interrupt mask. This has some performance
