Timed out waiting for debugger on first debugpy run

[connor4312]

Testing microsoft/vscode-python-debugger#35

This is the first time I used debugpy.

1. Attach to a process
2. After a few moments, there's a prompt from macOS asking something about enabling developer tools. I grant it.
3. In the meantime, the debug connection times out and results in a modal error

I have also been seeing this for the last few days.
I am starting debug from withing vscode. The first time fails, but subsequent tries to start debugging work.

I imagine this is gdb asking for permissions. If it works on second try, then that would be by design. If gdb doesn't let us inject the attach dll, it's not going to work.
