I don't have my manual handy but I thought WaitForPort() did what you want.
As for a Wait routine, what I have done is call the AmigaDOS wait command.
i.e.
address command 'wait 10'	/* a 10 second wait */

Do this in a loop checking for a particular condition (existence of a port,
another program finishing, etc.) every 5 or 10 seconds.  After a specific
number of loops (1 or 2 minutes worth) exit the loop and time out.

I hope this gives you some ideas.
