   This same ss20 has been able to build a kernel -j4 too, with an
   older SMP kernel:
   NetBSD 1.6L (HORN) #1: Tue Jan  7 21:46:16 CET 2003
       bouyer@pop:/local/pop1/bouyer/current/src/sys/arch/sparc/compile/HORN


it's build an arm world -j20 with this kernel, and a few other things
as well:

NetBSD 1.6M (_russian_) #719: Sun Jan 19 00:15:13 EST 2003
