        Tried the same with xterm 3.3.3 on i586, 64M RAM, 128M swap, continuously
    increasing the number of 'a's (perl -e 'print "a" x 60000', 600000,
    600000...).  But instead of xterm crash got Fvwm2 hangup after 6e6 "a"s.
    I.e. everything else works -- I ould even press the "play" button in x11amp
    with mouse, except Fvwm2.
    
        "strace -p <fvwm2pid>" shows that Fvwm2 waits infinitely on select().
    
        The only choice was to kill the window manager.
    
        All progs are from stock RedHat 6.0/i386 -- "Fvwm Version 2.2 compiled on
    Apr  9 1999 at 16:15:38".
