I suspect this will be the nanosleep in the heartbeat (there are
perror("nanosleep")'s in platforms/unix/vm/sqUnixHeartbeat.c and in
platforms/unix/vm-display/sqUnixXdnd.c.  First step is to add a line number
to perror, e.g.

    perror("nanosleep" " " __stringifyNum(__LINE__))

(__stringifyNum is in platforms/Cross/vm/sqAssert.h)

Then drill down further.  The above is very interesting.  I also see this
occasionally but only on linux.  Any and all unix experts please feel free
to look over my code in platforms/unix/vm/sqUnixHeartbeat.c and see if I've
done anything stupid.
