[3.15] gh-154139: Document that curses is not thread-safe (GH-154173) - #155690
Merged
Conversation
…onGH-154173) Whether curses is thread-safe depends on the library and how it was built. The blocking and refresh methods release the GIL, so with a non-reentrant curses, unsynchronized use from several threads can crash. The reference to window.use() and screen.use() is omitted: they were added in 3.16. (cherry picked from commit 1ed6b78) Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
