This removes a footgun in which users could attempt to transfer the
pooled ArrayBuffer underlying a regular Buffer, which would lead to
all Buffers that share the same pool being rendered unusable as well,
and potentially break creation of new pooled Buffers.

This disables this kind of transfer.

This removes a footgun in which users could attempt to transfer the
pooled ArrayBuffer underlying a regular `Buffer`, which would lead to
all `Buffer`s that share the same pool being rendered unusable as well,
and potentially break creation of new pooled `Buffer`s.

This disables this kind of transfer.

This doesn't cherry-pick cleanly onto v10.x-staging so would need a manual backport.
