If you're talking specifically about OTP, I'll defer to your  
experience.  But, in general, "make -j" works if you have correctly  
declared your dependencies in your Makefiles.  I'd have to say that it  
puzzles me why you could "make assumptions about build order" when  
make provides exactly a language for being explicit about such things.
