Matt Davis	1424484be0	Prevent stdio deadlock in forked children (#79522) ... * background threads writing to stdout/stderr can cause children to deadlock if a thread in the parent holds the internal lock on the BufferedWriter wrapper * prevent writes to std handles during fork by monkeypatching stdout/stderr during display startup to require a mutex lock with fork(); this ensures no background threads can hold the lock during a fork operation * add integration test that fails reliably on Linux without this fix	2 years ago
