The 'serverConnectionHandle' instance is then still alive, and holding on to a MachSendRight. waitUntilInitialized can then block (for the 30 second timeout) if the GPUP crashes, since notification of the crash doesn't happen until all send rights are destroyed (including the one on the stack). 1958927 1 mattwoodrow 2023-05-30 19:07:18 -0700 <rdar://109720377> 1958928 2 mattwoodrow 2023-05-30 19:16:36 -0700 Pull request: https://github.com/WebKit/WebKit/pull/14519 1959197 3 ews-feeder 2023-05-31 16:44:13 -0700 Committed 264766@main (50f865ffbe32): <https://commits.webkit.org/264766@main> Reviewed commits have been landed.
