Well, 
    consider that if you load them in one xml file then you will have a larger 
xml tree at runtime, ofcourse, after you are done with the GladeXML
object it shouldn't make any difference (unreffing the GladeXML should
free all resources and leave you with a functioning widget hierarchy), If you
want to re-create the popups every time you use them then you'll need to
seperate them into seperate glade files, this way you will gain on RAM
but loose on CPU (because your program will have to reload the glade file
every time for your popup).

    In my environment (an embedded jukebox system), we use one glade file
for each user "screen", and one glade file that we call "popups.glade", this 
makes sence from a CM's point of view as it is easy to manage and from an
implementation point of view it makes no difference because we keep all
widgets loaded in memory to reduce latency in the UI.
