Still, > I was obviously curious if I can lower that amount IOW, you sometimes see Emacs use an amount of memory you think is too large, but you have no idea whatsoever why that might be the case (IIUC you don't even know if it's really too large or if it causes a problem). There can be *many* different reasons, beside the fact that some freed memory is not returned to the OS. More to the point, whether the memory is returned to the OS or not is usually the least concern on a laptop or desktop machine. Stefan
