/ Mission Impossible Abseil
Robert, I have some news for you. Now this might come as a shock so you should possibly sit down and have a stiff drink. The Mission Impossible films are not based on life or fact, they are fantasy and made up. It is not possible for a belayer to easily pull someone back up.
Only way I can think of is assisted hoist, or ascending the rope. But you also have the issue of in the film doesn't he go down face first, so the harness is on backwards, you wouldn't want to be hanging like that for long while your belayer struggles to get you back up.
never tried it so not sure how viable it is
What you want is one of those land-rover winch things and a truck battery.
You will also want a venue where there's no risk of anyone else seeing you, and a partner who is sworn to secrecy. If word of these tendencies got onto, say, a public climbing forum you'd likely be ridiculed...
It's called a crane.
Run lowering rope through pulley wheel to reduce friction. Belayer lowers you fast, locks rope, then wearing heavy rucksack jumps off and you go back up.
There was a Dubliners song about this sort of thing.
As fictional a condition as Mission Impossible ....

There are a few dead people would disagree with you doctor
Case reference please?
Not quite a case reference, but the Health and Safety Executive did a study on this (Research Report RR708 - Evidence based review of the current guidance on first aid measures for suspension trauma, 2009) and found that it did in fact exist.
The Fire and Rescue Services Risk Assessment Guidelines specifically have a section on Suspension Syncope and reference this report.
A little Googling finds much more material.
So you don't know of a single case of suspension trauma? Funny that, after extensive research for that HSE 2009 study they didn't find any evidence of any cases occurring either.

How does the belayer get back up?
Me and a couple of mates tried a face-first abseil (with a Whillans harness!!!!!) in the mid eighties. It was only about 30 foot and redefined pain. Try it - just once, then you might rethink a long abseil and haul back up!

I'm assuming you don't have kids? :-O
We put on the harness backwards - we discovered how it is actually possible to make a Whillans even less comfortable!

Bloody hell, I bet you selfharm too :-D
Do you mean this kind of thing?:
For that you'd need a theatrical flying harness (as in Peter Pan) - its a very snug fitting, supportive harness with a swivel attachment on each hip which lines up with your C of G so you can hang in it at any angle. You can also just about see the coat-hanger (no seriously, that's what its called) above him in that pic.
Back in the day you'd have had counterweights and/or burly stage hands pulling a fat hemp rope instead of a belayer. These days its more likely to be a fast computer-controlled electric winch.
There's also a version with a big sort of swivelly belt that lets you pirouette as well. How much fun does this look? http://www.youtube.com/watch?v=bqRXFyY-hZQ
If you want one of those, you probably will be needing to rob a bank. ;o)
