The source file is src/sys/i386/i386/pmap.c, and it is in the
pmap_ts_referenced() function (a short function) at about line 2895.
I'm suspecting that a lock is needed.
I'll need to put a serial debugger on to go any further. Does this
work, or will I be wasting effort? (Getting that cable in is going
to be a _pain_).
