There's a philosophical point to be discussed here which you're skating
right over!  Should rust-in-the-linux-kernel provide the same memory
allocation APIs as the rust-standard-library, or should it provide a Rusty
API to the standard-linux-memory-allocation APIs?

Yeah, I think that the standard Rust API may simply not be acceptable
inside the kernel, if it has similar behavior to the (completely
broken) C++ "new" operator.

ISTM that having memory allocation failure cause a user process
to exit is a complete failure in something designed to run as
and kind of service program.

There are all sorts of reasons why malloc() might fail.
You almost never want a 'real' program to abort on one.
