Yeah, possibly. And now it looks like this has broken the Solaris 
buildfarm members too.

I'm curious to know how much all this buys us. One reason I haven't 
enabled parallel make in the buildfarm is that it interleaves the 
output, which can be a pain. And build speed isn't really the 
buildfarm's foremost concern anyway. I know waiting for a build can be 
mildly annoying (ccache can be a big help if you're building 
repeatedly). But I don't feel we need to squeeze every last pip out of 
the build system.
