I was aware of that prior to going over your PR, actually (though I
could really have left the unimplemented syscall alone, since it's not
even used in the automatic lint stub generation process). Any
comments/objections about tagging sys_sbrk() OBSOL and removing the
in-kernel stub? (If emulations should happen to depend on *not*
posting a SIGSYS if called (as it is now), this should be addressed
where required only.)
