The idea here is that, for the apps < 50, they're core desktop apps, and 
should be well-behaved, never ever ever crash on startup 
(hahahaha...ha...ha), and register with the SM in a reasonable amount of 
time.  So we can count on them not delaying desktop startup (under 
normal non-exceptionally-weird conditions).  At the very least, we 
'control' these apps and know who to yell at if they aren't being 

Apps > 50 are Any Old Random Apps, and we have no idea if they're going 
to play nice or not, or if they're going to delay startup because they 
forgot to register with the session manager, or if they even support 
session management at all (autostart apps will fall into this category). 
  At that point a splash screen might just say "Starting Other 
Applications", wait 750ms, and go away.  Or at least just wait until the 
last app has been spawned, regardless of whether or not it notifies us 
or not (and it could still write out the app names to the splash screen 
if it so chooses).  I think the splash screen is really only important 
for showing that the *desktop* is starting; once the WM, desktop, and 
panel are up, we assume the user can -- and wants to -- get some Real 
Work[tm] done, so the at that point splash screen will just get in the way.
