proc.$$.rlimit (rather than proc.curproc.rlimit) is your friend in that
regard.

The "what commands must be built-in" applies only when there's no
interface that lets a separate process affect the settings for the
shell.  When the interface is setrlimit(), that's so, but with sysctl a
child process _can_ affect the shell's resource limits.
