FWIW I've installed a few fixed cups into frames, both left and righthanded threads only snug- perhaps 20 ft-lbs of torque- and never had one loosen. Of course I don't believe in tightening pedals into crankarms really tight either... Some grease or better anti-seize compound on the threads will also facilitate later removal. I might have just been lucky so far though too I'll grant.
