Hi!
I recently upgraded my computer with a dual-core CPU. I've been enjoying 
nice decreases in compile time in my own projects by specifying --jobs=2 
when invoking make.

However, when I tried that with emacs it started compiling, very fast 
with both cores busy, but the build craps out (sorry, no log) after a 
little while. Maybe because it tries to build something that depends on 
something else that has not been quite finished yet because when 
multiple jobs are specified things doesn't happen in serial anymore? I 
don't know, but I know it works if I exclude --jobs=2. But then emacs is 
built and the total cpu utilization is only 50 percent. :-( Is there a 
way I can utilise both cores when building emacs? I bought the new 
processor mostly to get improved compile time performace. :-)
