Let's clear the air here. Re-checking the torque isn't tightening anything. As long as the fastener hasn't loosened from the original torque value simply applying a torque wrench to it and determining that it is still tight runs no risk of damaging a fastener's threads or whatever it is threaded into.
Where the problem comes is from a person wanting to see a turn on the wrench every time he/she 'checks' the tightness. Doing that multiple times will assure that the fastener, or whatever it is threaded into will eventually fail.
If a good quality torque wrench is used and the setting is the same as the original value then the wrench will let you know if the fastener has loosened or not. If it hasn't then leaving it alone won't compromise anything. If, however, the torque value is exceeded, or if you're using a cheap discount store torque wrench that doesn't always read the same, you stand a chance of damaging the fastener or threads.
Any fastener that is subjected to heat/cool cycles, such as cylinder head bolts, intake or exhaust manifold fasteners should be 'checked' periodically because the heat/cool cycles can change the tightness due to expansion and contraction. By 'check' that means seeing if the original torque value is still there. It doesn't mean getting another turn or half turn, or even a quarter turn on the wrench.
Anyone disagree?
