652 012a8a02 2004-10-22 devnull * BUG. Actually there's no bug here but this is the
653 012a8a02 2004-10-22 devnull * first place you'd look. When a program is run,
654 012a8a02 2004-10-22 devnull * it doesn't disappear from the main tag until the
655 012a8a02 2004-10-22 devnull * mouse is moved or keyboard is hit. This would
656 012a8a02 2004-10-22 devnull * suggest that the WWait case isn't working right,
657 012a8a02 2004-10-22 devnull * but what's actually going on is that the X11 code
658 012a8a02 2004-10-22 devnull * is running a select-based threading loop that
659 012a8a02 2004-10-22 devnull * doesn't get interrupted until there is data from X11.
660 012a8a02 2004-10-22 devnull * This was done to make acme work on Suns and
661 012a8a02 2004-10-22 devnull * other systems where our threading was sub-par.
662 012a8a02 2004-10-22 devnull * Now that we've gotten pthreads working (sort of),
663 012a8a02 2004-10-22 devnull * we might be able to fix this properly.
664 012a8a02 2004-10-22 devnull * But the bug is in libdraw and libthread, not here.
