waitpid() is a routine specified by POSIX 1003.1.  It adds to wait() some of 
the functionality of wait3(), namely the use of wait3 options.  It also lets 
you specify a set of child processes for which status is requested, i.e. a
process with a specific pid or process group ID.  It's my understanding that it
will make it's appearance in SysV R4 or any OS thats going to be POSIX 1003.1
compliant.
