Review comment:
This is incorrect. This mean that there will be a copy of the getopt()
variables in every thread right? But only the copy in the main thread will
used. This seems wrong.
Before your questionable change, there was a single copy of the getopt()
variables in the main thread created by up_stack_frame. Each thread pointed to
that single copied. But it looks like you have ruined that. Your solution is
incorrect.
