It uses python subprocess.Popen() capturing stdout and stederr to a pipe, but then that pipe is never checked because the browser is not expected to end. So if the browser outputs lot of lines either to stdout or stderr it will cause the pipe to become full and then the browser process will get frozen. I reported this originally at https://github.com/Igalia/cog/issues/589 thinking it was a bug on Cog, but is a bug on the tool used to run the browser. 1965535 1 clopez 2023-07-07 05:29:38 -0700 Pull request: https://github.com/WebKit/WebKit/pull/15628 1965550 2 ews-feeder 2023-07-07 07:13:00 -0700 Committed 265839@main (0f3437e25ccf): <https://commits.webkit.org/265839@main> Reviewed commits have been landed.
