I am committing the following change to the main trunk. After some preliminary testing, it appears to be non-fatal when swallowed, and speeds up redisplay a lot. Hoewever, lots of code might already rely on the current behavior, so please watch for display glitches this may cause. This change enables preemption check during lazy redisplay. -kkm RCS file: /usr/CVSroot/XEmacs/xemacs/src/redisplay.c,v retrieving revision 1.64 diff -u -r1.64 redisplay.c --- redisplay.c 2001/05/24 07:51:27 1.64 +++ redisplay.c 2001/05/30 23:36:08 ＠＠ -6473,7 +6473,7 ＠＠ { if (CLASS_REDISPLAY_FLAGS_CHANGEDP(f)) { - int preempted = redisplay_frame (f, 0); + int preempted = redisplay_frame (f, 1); if (preempted) return 1; } ＠＠ -6502,7 +6502,7 ＠＠ { if (CLASS_REDISPLAY_FLAGS_CHANGEDP (f)) { - int preempted = redisplay_frame (f, 0); + int preempted = redisplay_frame (f, 1); if (preempted) return 1; }
