>>TITLE XUngrabServer CH07
void

Display	*display = Dsp;
>>ASSERTION Good A
A call to xname
resumes processing of requests and close downs on other connections.
>>EXTERN

#include	"Xatom.h"

>>STRATEGY
Create second connection client2.
Call XGrabServer on default display.
Create another process.
  In created process:
  Perform a XChangeProperty request for client2.
Wait sufficient time to allow client2 request to be processed.
Check that no PropertyChange event has been produced.
Call xname to Ungrab server.
Wait sufficient time to allow client2 request to be processed.
Verify that event has now been received.
