Well, after crashing once today, I decided to turn off autosave. I know what you're saying; "That's crazy!!!". Well, I haven't seen one crash in over 4 hours since turning it off. I save pretty regularly anyway, so I don't need autosave in there causing problems. Who knows, maybe it's not autosave, but I'm banking on most of my problems with all the crashes having come from two calls happening at the same time and Autocad not knowing how to handle that.
