[nycbug-talk] multiple make buildkernel

I have a quad processor box that is fairly slow cpu-wise.  I am using  
the make buildworld -j option (benchmarks so far are 47 min 9 sec at  
j11, 47 min 18 sec at j10,  47 min 5 sec at j9, still playing with  
this).  Buildkernel seems to take an hour and half at least.  I am  
wondering what would be involved to get multiple buildkernel's to run  
for different kernels.  I believe a make buildkernel only writes to / 
usr/obj/usr/src/sys/KERNELNAME.  If this is true, it should be okay  
for multiple buildkernel's to run, right?
