The wait isn't performed in parallel for all the argument PIDs at once
(it's not like doing a select() on a list of file descriptors).  Rather
the shell waits for each PID in the order it appears on the command
line, before attempting to wait on the next one.

See zsh-workers/27442 and its thread for possibly-related discussion;
there doesn't appear to be a requirement that the shell keep track of
more than one already-exited asynchronous job.
