Race condition for ScheduleDestroy events when reseting the environment

[Kakadus]

Resetting a running environment sends a close_command to the simulation. Then, the ns3 simulator is destroyed, and all ScheduleDestroy events should be handled:

ns3-ai/model/gym-interface/cpp/ns3-ai-gym-interface.cc

Lines 210 to 211 in 7dc5b1b

	Simulator::Stop();
	Simulator::Destroy();

In parallel, the experiment is runned again, which kills the old environment and interrupts the ScheduleDestroy events.

ns3-ai/python_utils/ns3ai_utils.py

Lines 147 to 148 in 7dc5b1b

	def run(self, setting=None, show_output=False):
	self.kill()

Instead, I expected that all events scheduled with ScheduleDestroy are executed when I reset the environment. It would be a nice feature to execute these events, when I close the environment.
