Overall these patches trim about 250 lines from the C source code, and should improve efficiency by not creating objects on the heap to handle stack-related events such as implementing save-excursion. This patch also removes primitives like 'free_misc' that ask for trouble by second-guessing the garbage collector. I'm filing this as a bug report in order to give the patches a bit of time to cool before installing. Comments welcome, as usual.
