 // AuthorizationExecuteWithPrivileges fork()s and exec()s the tool, but it
 // does not wait() for it.  It also doesn't provide the caller with access to
 // the forked pid.  If used irresponsibly, zombie processes will accumulate.
 //
 // Apple's really gotten us between a rock and a hard place, here.
 //
 // Fortunately, AuthorizationExecuteWithPrivileges does give access to the
 // tool's stdout (and stdin) via a FILE* pipe.  The tool can output its pid
 // to this pipe, and the main program can read it, and then have something
 // that it can wait() for.
 //
 // The contract is that any tool executed by the wrappers declared in this
 // file must print its pid to stdout on a line by itself before doing anything
 // else.
