Just a note about this: It is possible that we can do something similar on 
Linux in the future, since the Linux kernel may be gaining an interface called 
‘memfd’ for memory backed file descriptors, which is apparently required for 
their kdbus stuff. I’ve briefly glanced over the code, and if I read that 
correctly, it's just anonymous shared memory regions with an additional 
interface allowing you to ‘seal’ them (i.e. mark them as read-only). No idea 
why this couldn’t be done as part of the traditional POSIX shm API, but I will 
keep an eye on it just in case it proves useful.

Cheers,

Niels
