Historically, there was once an attempt to rework POSIX into a separate
language-independent definition and language bindings (for C, Fortran, Ada
etc.), but I don't think it got anywhere, and it's probably doubtful
whether the idea was ever very practical. (See the introduction to
POSIX.1:1990, for example: "Future revisions are expected to contain
bindings for other programming languages as well as for the C language.
This will be accomplished by breaking this part of ISO/IEC 9945 into
multiple portions---one defining core requirements independent of any
programming language, and others composed of programming language
bindings.".)

Yes, we should have a few new syscalls to set these ids at the process
level.
