When I do an xloadimage -onroot, how do I later free and get rid of
the pixmap on the root window?

I noticed xloadimage does an
   XSetCloseDownMode(dpy, RetainPermanent);
so that the pixmap will not be freed when it exits.

It also puts a property on the root window with the pixmap id.
"xprop -root" returns:
   XA_XLOADIMAGE_COLORS_XID(PIXMAP): pixmap id # 0x1500003

If I do an "xkill -id 0x1500003", will that free the pixmap?
The image remains on the root window after I do this.
Is it still using memory in the server?
If I do an "xsetroot -solid blue", the root window clears to blue,
but is the pixmap I previously loaded with xloadimage still
wasting memory?

Thanks,
Andrew
