heh, not that I ask for change, but out of curiousity: What is 
the use of different desktop geometry for each desk ? I'm pretty sure that 

most (if not all) window managers will not support it, making all the 
desktops
the same size. 
For this window managers, would not it cause race condition, 
when Pager will endlessly try to "correct" geometry to really be 
different, 
despite the fact that WM always makes it the same ?
like:
Pager :                 sets geom of desk 1 to 1024x768, desk 2 to 
2048x1536 
window manager:   sets everything to 2048x1536
Pager :                 checks property and sees that geometry is 
incorrect for desk 1
Pager :                 sets geom of desk 1 to 1024x768
window manager:   sets everything to 1024x768
Pager :                 checks property and sees that geometry is 
incorrect for desk 2
Pager :                 sets geom of desk 2 to 2048x1536 

and on and on and on....
