This isn't new behaviour from the BPF people.  They always go their own
way on everything.  They refuse to collaborate with anyone in MM to make
the memory allocators work with their constraints; instead they implement
their own.  It feels like they're on a Mission From God to implement the
BPF Operating System and dealing with everyone else is an inconvenience.
