I understand now.  The way that the xpbproxy works is very similar to  
a CLIPBOARD_MANAGER, and it does greedy CLIPBOARD management.  By  
greedy I mean whenever the CLIPBOARD selection owner changes, the  
xpbproxy grabs the selection data, and sets itself as owner of  
CLIPBOARD with that data.  This enables easy copying of images and  
other CLIPBOARD data from X11 to pbs/NSPasteboard, and eliminates the  
need for 2 Copy menu items (for PRIMARY and CLIPBOARD) for XQuartz.

If you really need selectToClipboard in your ~/.Xresources, as well as  
the text to remain selected/owned, then I don't see a way around it  
with the current xpbproxy design, beyond disabling proxying of  
clipboard which probably isn't what you want.
