@bcmills requested issue #45211 to be considered for backport to the next 1.16 minor release.

@gopherbot, please backport to 1.17 and 1.16: this is a race condition that can result in deadlocks on ARM64 in any process that relies on Close unblocking a read. It is tricky to diagnose (and hard to reproduce reliably), and there is no apparent workaround for users on ARM64 machines.
