"The third and last process control system call used by the Shell is

      processid, status = wait()
This primitive causes its caller to suspend execution until one of its children has completed execution. Then wait returns the processid of the terminated process and a status value indicating how the process died. (Processes which are never waited for die unnoticed and presumably unmourned)."

A lost opportunity to give C multiple return values.

Um, structs?

typedef struct { pid_t pid; int status; } wait_t;

wait_t status = wait();

Tuple support, which in essence are anonymous structs, would have been very nice in C, too.
