pTools Process Execution Wait Utility (pwait)


Based off the Sun Microsystems pwait utility.  Wait for all of the specified 
process to terminate.

Usage:
	pwait [ -v ] pid ...

NOTES:
	- Initial implementation using select()/poll() as done in Solaris
		- This does not work as the select()/poll() is not notified
		when the process exits so we wait forever if no timeout is given

	- New implementation will be to implement a /proc specific select()/poll()
