Some time ago, Hrvoje Niksic wrote... It appears that symbols declared with DEFVAR_BOOL and DEFVAR_INT are not restored by the dumper, so their value is 0 after loading the dmp file. It does not look to me that these variables are saved by the dumper at all, although I may be missing something. May I please hand it over to O.G. :) A question: does mmap gives any performance benefits over read when loading the dump file? NT is primarily a single-user system, so the case of 2+ xemacsen should be rare, and the shared memory benefit would not pay off. I will fake mmap if it gives performance benefits though, even a little. Startup seems to be slower a bit. Big K
