The suspend-emacs documentations contains several claims that are not
true on some non Berkeleyish systems: "superior process", etc...

|suspend-emacs:
|Stop Emacs and return to superior process.  You can resume.
|If optional arg STUFFSTRING is non-nil, its characters are stuffed
|to be read as terminal input by Emacs's superior shell.
|Before suspending, if `suspend-hook' is bound and value is non-nil
|call the value as a function of no args.  Don't suspend if it returns non-nil.
|Otherwise, suspend normally and after resumption call
|`suspend-resume-hook' if that is bound and non-nil.

Also it should mention how on a Berkeleyish system one can get
suspend-emacs's SYS Vish behaviour: making a sub-shell (or perhaps
just going to the superior shell), and cd'ing to default-directory.
