I just checked what top does on SunOS, when a program has more than 999
threads and it seems to clip the number of threads to 999, as if
something min(999, numthreads) is what is printed :-)

I'll change the width of THR to 4 columns if that's enough to fix the
wrapping issue of COMMAND, or even to 3 if that is not enough.  Clipping
the value of numthreads to something less than or equal to 999 is also a
relatively good idea that shouldn't be too hard to implement.
