it's by design that the execution context for new threads to be empty or
should it be possible to set it to some initial value? Like e.g:
var = new_context_var('init')
def sub():
assert var.lookup() == 'init'
var.set('sub')
def main():
var.set('main')
thread = threading.Thread(target=sub)
thread.start()
thread.join()
assert var.lookup() == 'main'
Thanks,
