wait process

can any one please give me clear idea of wait process in UNIX system.
I am using AIX 5.3 and see loots of wait process. I have very basic concept of wait process. If CPU has nothing to do then a wait process is generated per CPU. But i want know the detail how is it forked.
Is wait a jombe process?
does loots of wait results pagefaults?
please refer any documentations or replies...
thanks and regards

EXIT(2) 							System Calls Manual							   EXIT(2)

NAME
exit, _exit - terminate a process SYNOPSIS
void _exit(int status) DESCRIPTION
_exit terminates a process with the following consequences: All of the descriptors open in the calling process are closed. This may entail delays, for example, waiting for output to drain; a process in this state may not be killed, as it is already dying. If the parent process of the calling process is executing a wait or is interested in the SIGCHLD signal (Minix-vmd), then it is notified of the calling process's termination and the low-order eight bits of status are made available to it; see wait(2). The parent process ID of all of the calling process's existing child processes are also set to 1. This means that the initializa- tion process (see intro(2)) inherits each of these processes as well. Most C programs call the library routine exit(3), which performs cleanup actions in the standard I/O library before calling _exit. RETURN VALUE
This call never returns. SEE ALSO
fork(2), sigaction(2), wait(2), exit(3). 4th Berkeley Distribution May 22, 1986 EXIT(2)
