Hmm, I think I was confused by seeing kernel builds intermingle with the 
associated modules.  sys/modules/Makefile uses bsd.subdir.mk.  I think I see 
similar things in world builds where I will see parallel builds of bin vs sbin 
vs usr.bin vs usr.sbin, but within each of those directories the builds go 
sequentially.  I think you would need to change bsd.subdir.mk if you want to 
fix this.
