	"""
	Example of running an embedded IPython shell inside an already-running trio loop with working autoawait (it's handy
	to be able to start an interactive REPL with your application environment fully initialized). This is a full solution
	that works around https://github.com/ipython/ipython/issues/680 (see
	https://gist.github.com/mikenerone/3640fdd450b4ca55ee8df4d4da5a7165 for how simple it could be). This bug should be
	fixed IMO (using atexit is a questionable design choice in the first place given the embedding feature of IPython
	IMO). As it is now, the entire IPythonAtExitContext context manager exists only to work around the problem,
	otherwise it would result in an error on process exit when IPython's atexit-registered method calls fail to save the
	input history.

	Example of running an embedded IPython shell inside an already-running trio loop with working autoawait (it's handy
	to be able to start an interactive REPL with your application environment fully initialized). This works as is,
	and it really should be this easy. Unfortunately, due to https://github.com/ipython/ipython/issues/680,
	this currently results in an error on process exit when IPython's atexit-registered method calls fail to save the
	input history. This bug should be fixed IMO (using atexit is a questionable design choice in the first place given
	the embedding feature of IPython IMO). Sadly, working around it is significantly less trivial. See
	https://gist.github.com/mikenerone/786ce75cf8d906ae4ad1e0b57933c23f for an example of that full solution.
