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

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

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