I used to do this for very long stretches, longest I remember is while building a 'softmodem' but I paid for that by nearly falling down two flights of stairs.
The last couple of years the longest I've been able to manage was probably a couple of hours, 3 or 4 at best.
The thing that will get me out of my concentration almost invariably is some kind of sound. When I really sit down to hack I exit (not minimize) all software that might distract me, and I like to work like that at night, which doesn't help because it screws up my day/night rhythm and then it can take me a long time to get back to 'normal'.
