Agreed, but I was only responding to the comment that building on an SSD
was no slower than tmpfs.

I can't agree with the second part, a tmpfs has far less space than a
disk. I had a gcc build fail this morning when /tmp filled up. Not
because gcc needs more than I had but because another emerge had failed
and left a G or two in /tmp. You'll always have more disk space than 
RAM - embedded aside.
