Original Pull Request: https://github.com/microsoft/terminal/pull/5286

State: closed
Merged: Yes

When the connection printed text immediately, synchronously, as part of
Start() it would cause terminal to deadlock. We should start the
connection outside of lock.

The ConptyConnection would do this when it failed to launch something
(trivial repro: wt -- xyz).

The TelnetConnection would do this all the time, because local loopback
telnet is fast and easy.
