When "arc" receives SIGWINCH or other signals during display of a prompt, recover

Authored by epriestley on Jun 5 2020, 11:07 PM.



Ref T13546. Resizing the terminal window to send SIGWINCH, or other signals, may interrupt "stream_select()" with an error which upgrades to a RuntimeException.

When "stream_select()" fails, continue and test the stream itself.

Test Plan

Waited for a prompt, resized the window. Before patch: SIGWINCH interruption. After patch: undisturbed prompt.
