We already avoid launching prewarmed processes when the system is under memory pressure. However, this really only works as intended on iOS because we're not listening for all the memory pressure notification on macOS. Also, we should return early in WebProcess::prewarmGlobally() if the system is under memory pressure now that the process has been launched. 1743596 1 webkit-bug-importer 2021-03-24 16:30:25 -0700 <rdar://problem/75810423> 1743597 2 424199 cdumez 2021-03-24 16:41:19 -0700 Created attachment 424199 Patch 1743802 3 ews-feeder 2021-03-25 09:49:52 -0700 Committed r275038: <https://commits.webkit.org/r275038> All reviewed patches have been landed.
