Because wait ...
...waits for a child process to terminate and returns the pid of the deceased process...
So while child process A dies and it returns some PID > 0 child process B continues to run. It will return -1 when there are no child processes. Unlikely to happen, but since it is linked to wait(2) - a possibility, perhaps?
