Subject: [PATCH] Cygwin: pty: Fix deadlock caused by Ctrl-C in setup_pseudoconsole().
Date: Mon, 18 Apr 2022 20:49:58 +0900 [thread overview]
Message-ID: <20220418114958.28630-1-takashi.yano@nifty.ne.jp> (raw)
- If Ctrl-C is pressed just after setup_pseudoconsole() is called,
mintty stops to respond a while when CPU load is high. This patch
fixes the issue.
