Bug Fixes
- Fixed Chrome being killed after ~10s idle on Linux caused by
PR_SET_PDEATHSIGtracking the blocking thread that spawned Chrome rather than the daemon process. When Tokio reaped the idle thread, the kernel sent SIGKILL to Chrome even though the daemon was still alive. Orphan cleanup is handled by the existing process-group kill inChromeProcess::kill()(#1157, #1173)
