See sys.dif.gz in ~bde on freefall. For optimizing userret(), the idea is to set flags for ast() to check. E.g., there is a flag for signals so that usrret() doesn't need the CURSIG() loop. CURSIG() is much more expensive than it used to be, since it has to check 128 signals instead of 32 and aquire and release 2 locksE.g., there is a flag for signals so that usrret() doesn't need the CURSIG() loop. CURSIG() is much more expensive than it used to be, since it has to check 128 signals instead of 32 and aquire and release 2 locks instead of none. > On Sun, 20 Jan 2002, Bruce Evans wrote: > > > On Sat, 19 Jan 2002, Alfred Perlstein wrote: > > > > > * Julian Elischer <julian@elischer.org> [020119 10:01] wrote: > > > > > > > > On Sun, 20 Jan 2002, Bruce Evans wrote: Please don't top post (top mail?).
