We had a discussion along these lines when refactoring elisp compilation: in the past it was all done in one big batch. Now it's done with an emacs invocation per .el file. The result of that discussion was that while you slow down single core machines, the new way of doing things fits make's model much better: instead of fiddling around with stamp files, the Makefile just has a suffix rule. IMHO, your point is valid, but to do it safely would require a tool smarter than make. -- Jack
