The user may also see a performance gain on Linux if they use a less stupid allocation scheme. I ran into some code once that read strings one character at a time via getc() and did a realloc for each read. Needless to say, performance was truly awful since a typical run required parsing over 600MB of text. I saw a better then 50% speedup on Alpha Linux when I fixed that mess. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
