okay, loctite is not the ideal solution by any means, but there's definitely a lot of fud about them. your loctite job should be perfectly safe IF

1. you have hand brakes. i mean, "duh".
2. both sets of threads were cleaned really well with degreaser before the cog was threaded on with the loctite
3. the bike was not ridden for 24 hours after the cog was put on
4. the cog was tightened on properly the first time. ie. with a chainwhip and big arms.

a suicide hub is not, despite the name, necessarily a dangerous thing. if done properly, your loctite job should hold perfectly well... and even if it does fail, all that's going to happen is that your going to lose your drivetrain. now, if you don't have hand brakes, that's a formula for death. but you have hand brakes, right? so, having your hub unthread will be an annoyance, but certainly not a death sentence.
