Is make-frame async?

Is make-frame async?

[PT]

I tried creating a new frame and setting the mouse pointer to its 0,0  
position in 21.3 on Linux:

(let ((frame (make-frame ...)))
   (set-mouse-position frame 0 0))

Sometimes it works, sometimes the pointer is put into the 0,0 corner of  
the desktop instead.

Maybe make-frame returns before the frame actually appears? The  
documentation doesn't say so.
If this is the case is there a standard way to wait for the frame "to be  
ready"?

I thought about polling it with frame-visible-p, but this method doesn't  
seem too elegant.

Is there an other way?

This is probably what you want to try.
