That is different in FSF Emacs isn't it? No, it doesn't. I copied most of the code, but I did not copy the part that unconditionally disabled mmap for allocation. Instead, I forced mmap allocation off before dump, when it is absolutely unsafe, and I forced the use of minimal tag bits so that it could be used after dump. This code has had very heavy testing by me and many others for 15 months now. I am fairly confident about its stability. We can, I suppose. voodoo_free_hook is ugly, but it works. What we really want is to not dump at all. What's the current status of getting rid of dumping? -- I protest the NATO war in Yugoslavia.
