It would seem to be a reasonable thing to do and >the manual page does not indicate that "-n" is a default option. Yes: it is not really all that reasonable. The 4.2 ld default is `-z': demand paged. `-n' makes the text shared, but not demand paged. Instead, on startup, the entire text is copied in to memory. If Emacs were to touch all its pages on startup, that would be sensible, but both Gnu and locally-hacked-Unipress touch only about half their pages. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) UUCP: seismo!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@mimsy.umd.edu
