Right, and when I have capslock mapped to control as I usually do, then
I do get a keyup event:

Capslock turning on:
sdl_process_key({type=0x2,which=0x0,state=0x1,keysym={scancode=0x42,sym=0x12d,mod=0x2000,unicode=0x0}})
keycode = 0x3a
kbd_put_keycode(0x3a)
kbd_put_keycode(0xba)

capslock turning off:

sdl_process_key({type=0x3,which=0x0,state=0x0,keysym={scancode=0x42,sym=0x12d,mod=0x0,unicode=0x0}})
keycode = 0x3a
kbd_put_keycode(0x3a)
kbd_put_keycode(0xba)

Actually, I may not get a chance for another two weeks. Can we
get someone else to test?
