Re: [PATCH] Handle DAP "stepOut" request in outermost frame

Another way might be to revisit this idea, documented in a comment in
next.py:

# This is a server-side request because it is funny: it wants to
# 'continue' but also return a result, which precludes using
# response=False.  Using 'continue &' would mostly work ok, but this
# yields races when a stop occurs before the response is sent back to
# the client.

That is, solve the stop event race by deferring such events, and then
have all stepping commands add "&" for background execution.  Then they
could all be ordinary requests (on the gdb thread with response), and
any exceptions thrown early by the commands would affect the response.
