About once every 6 months for us. To be fair, a major release might require a tad more work than usual once every 2 months (think 1-2 extra hours per day that week).
I think the key to making it work is keeping it small. If there were too many people, nobody would feel individual responsibility and it would devolve into a nobody comes into work culture.
As it is, some people come in to work at 9 and leave at 4:30, some 9-6, some 11-8, some 2-2 (whoops, that's just me :) -- depends on when you like to work.
Also, everybody has easy weeks and hard weeks, and there's no point sticking around work if you've got nothing to do. Much better to work hard for 4 hours a day on the easy weeks than stick around for an extra 4 hours depressed.
