Ptvsd should handle disconnect request

 1> [DebugAdapter] <--   E (exited): {"type": "event", "seq": 19, "event": "exited", "body": {"exitCode": 0}}
 1> [DebugAdapter] <--   E (terminated): {"type": "event", "seq": 20, "event": "terminated", "body": {}}
 1> [DebugAdapter] --> C (disconnect-14): {"command":"disconnect","arguments":{},"seq":14,"type":"request"}

we currently exit process after sending terminated event.

Interestingly this this isn't causing an issue with VS Code. Ideally we should get some error such as The debug adapter exited unexpectedly.
@karthiknadig are you getting any error messages in VS (such as the one I've mentioned above)?

Either way, I'd consider this to be a show stopper for VS Code, as this (not ending debug session correctly) could lead to errors being displayed by VS Code.

I agree w/ @DonJayamanne that this is probably a showstopper for releasing experimental.

[karthiknadig]

@DonJayamanne yes, I get that error message. I filed this bug for that reason.
