Is there a way (using Xlib or Xt) for my application to be notified
whenever the owner of the PRIMARY selection changes?  Or better yet,
when the selection itself changes?

I'd like to be able to update my application's menus based on the
available selection targets.  To do this, I need to know when the
available targets have changed, which is likely to be when the
selection changes.

After looking through the ICCCM and a couple of Xlib and Xt
references, it appears to me that the only way I can receive
notification of selection status is to actually own the selection
myself (in which case I'll be told when I lose it).  That's not what
I want to do.

Thanks in advance for any ideas.
