 This is single (in the guest) or double (guest + host) keyboard autorepeat
 together with low timer precision (qemu can only emulate hz/2 events per
 second if the host isn't tickless).
 
 Turning off keyboard repeat in the guest console with
 
 wsconsctl -k repeat.del1=0
 
 or if you run xterm on the guest with
 
 xset r off
 
 works around this problem.
 
 Another method is to use a serial console.
