A better question would be, whether there is a way to turn it off?
Under 99% of our use cases i don't really care that argv[0] is
replaced, except when GPU's are concerned.

when you run nvidia-smi, instead of seeing which program is attached
to which gpu, it only shows the condor exec strings, which is
annoying, but doesn't actually impact anything
