kernel - Change default kern.ipc.shm_allow_removed=1
* Change kern.ipc.shm_allow_removed to default to enabled. This feature
allows a shared memory segment to be located by its shmid after being
deleted, as long as some prior reference to the segment is still active.
* Primarily used by chrome these days, this trick is convenient in that
it allows applications to attach shared memory segments in a manner that
do ensures they are deleted if the application is killed or seg-faults
unexpectedly.
