The posix_spawn bindings should go into core:sys/posix. When I did that package I thought this header was not useful for Odin because of this quote:

The posix_spawn() and posix_spawnp() functions are used to create
a new child process that executes a specified file. These
functions were specified by POSIX to provide a standardized
method of creating new processes on machines that lack the
capability to support the fork system call. These machines
are generally small, embedded systems lacking MMU support.

But I see (and you explained in Discord) that it actually has uses.
