[Bf-funboard] Loading Screen for Blender

On my slightly-beefy linux machine it takes 9 seconds if I haven't 
started blender in a while, and a little under 1.5 seconds otherwise. 
(counting from launch to until blender is fully usable).

I'm guessing there's some disk caching going on which is helping 
alleviate the symptoms of my somewhat slow harddrive.
If this is true, then at least on my system it appears IO is the main 
bottleneck. With an SSD the times would likely be consistently nearer 
the 1.5 second end of the spectrum.

On a positively ancient laptop that no one would/could reasonably use 
blender on, it takes 2 seconds for the window to appear and 8 seconds 
for it to finish drawing (this laptop doesn't have a function GPU, and 
software rendering everything is extremely slow), a total of *10 seconds*.

On first run (without any disk caching) it takes 20 seconds for the 
window to appear and 19 seconds before drawing the UI and being 
technically "usable", a total of *39 seconds*.


For comparison, gimp on my slightly-beefy machine takes about 2.5 
seconds to become usable. Audacity even less at about 1.5 seconds.

It's worth noting that on the first run in a while, there is usually a 
long delay filled with disk activity before the splash screen of either 
gimp or audacity even appears. I imagine this is similar to the 7.5 
second delay blender sometimes experiences.

This makes me wonder if the delay caused by slow IO operations is even 
practically progress-bar-able. Chances are it'd end up being one of 
those progress bars that doesn't move for 10 seconds then jumps to 
complete all at once..
