Changing malloc_size.rs means we essentially "fork" from the Servo version (we're at commit 5bdea7dc1c80790a852a3fb03edfb2b8fbd403dc).
That's not necessarily a problem but something we should be aware of (and clean up that code comment and maybe the readme?).

A few minor nits and then there's the matter of testing #[ignore_malloc_size_of = …].

AFAIR #[derive(MallocSizeOf)] actually worked if we renamed parity-util-mem to memory_size_of (example), but I agree it is a hack.

Yeah, hacky, might bring some issues later

Lgtm too, about the way to include external module (parity-util-mem) into the derive macro, I like the current substrate way of doing thing (since we got the derive macro in our code base we can probably use it now): https://github.com/paritytech/substrate/blob/20a9b15cdbed4bf962a4447e8bfb812f766f2fbc/frame/support/procedural/tools/src/lib.rs#L34 (I do not remember to well how it works but it is actually well tested on substrate).
With the code forked, it may be also possible to add a serde like implementation for a specific field with a function (I remember some discussion about it and I am not sure it is worth the work).

You mean #255? Yeah, it's possible to implement it now.
