When the client has actively grabbed the  device,  then  a
call  to UngrabDevice releases the device and any queued
events.
>>STRATEGY
Create grab window.
Grab and freeze device.
If no extensions:
  Touch test xname.
else
  Press and release key.
  Call xname.
  Verify that events are released.
  Create new window.
  Verify that device events can be received on it.

>>ASSERTION Good B 3
When the specified time is earlier than	the  last-device-
grab time or is later than the current X server time, then a
call to UngrabDevice does not release the device and any
queued events.
>>STRATEGY
Get current time.
Grab device and freeze other devices with this time.
Call xname with earlier time.
Verify that the pointer is still frozen and therefore device grab is not 
released.

Get current time and add several seconds to get future time.
Call xname with this time.
Verify that the pointer is still frozen and therefore keyboard grab is not 
released.
