I found the following hack, but there's some odd things about it. Gonna list the code and the pros and cons, and see if anyone can jigger around with it to maximize pros and minimize cons.

PROS:
A) Normally when you loot a chest, it pops out the loot bags/gold and that's it. With this cheat, it would appear you can loot a chest indefinitely. Need to test to see if #items has a positive correlation with time spent in the looting animation. But you get tons of items for just standing at a chest after you loot it. Great if the last thing you do before you go to sleep is go in the Fortune Door and loot an epic chest. Wake up the next day and you should have a shartload of items. Go through, equip the best stuff you can, and use the admin command emptyBags to sell off every equip you're not wearing. WARNING: if you're saving an item but not wearing it (too low-level to wear it, or whatever) then the emptyBags command WILL sell it. Be careful.
B) Also normally, when you open a chest or pick up a pile of gold, it gives you 1xp for your trouble. If you loot chests/gold/etc. with this cheat, it gives xp for as long as the item remains on the screen. It seems the chest disappearing triggers the xp to stop counting up. I get about 300xp per chest opened. The same goes for really anything you can interact with that gives xp - chests, coins, people, ingredients, etc. Rejuv plants don't give xp.
C) It does NOT show coins/lootbags/collect-text. Good as a lag-reducer, bad if you want to know what you're actually collecting.
CONS:
A) You don't know what you're collecting, and because the lootbags/coins don't show, your inventory/goldcount don't actually update until you reload. The items/gold ARE there, though.
B) For whatever reason, it causes the damage effect of the F1 admin hack to only be applied to one monster at a time, so while the loot mechanics would be a great lag-reducer for the infini-spawn cheat, even holding down F1 you can't even get CLOSE to killing everything faster than they spawn. When too many mobs spawn, game crashes.
C) Also, because any interactions aren't kept track of, if you're looking for items/killing monsters/meeting someone for a quest, that won't register either, so you need to use the missionComplete command to do that. You can still complete any mission with a countdown clock regularly though.
Again, if any one can check into it to see why it's doing what it's doing, and modify the cheat so it makes the pros better and eliminates some of the cons, that'd be great.
For the record, that bit of code is found in lib->character->model->character in the killMonster function.
EDIT
Also:
USING CONSUMABLES IN-LEVEL DOESN'T USE THEM UP (does NOT work with energy-giving items)
