Description Brent Fulgham 2021-02-17 17:34:27 PST 
A set of ipc-posix-shm-read-data rules were added long ago to support cookied communications, but we do not interact with this process in the WebContent process and should have no need for them.

Telemetry has not uncovered any uses, so let's start blocking and confirm.
