    - return early in xcall() if the function is sparc_noop() instead of triggering
      the IPI and then ignoring responses ( or lack thereof )
    - write the .tag field last to avoid a race when polling for an incoming
      IPI
    - add event counters for IPIs being caught with the mutex not held, and for
      messages that are already marked as completed
    With this my SS20 made it through 48 hours of pkgsrc with MAKE_JOBS=3 and a
    pair of SM81s.
    Hypersparcs still crash but instead of craziness we get actual error messages,
    apparently one CPU will occasionally do a watchdog reset, which according to
    the manual is caused by catching a trap with traps disabled. Now to figure
    out how that can even happen...
