Improved Process Killing Under Windows 2000
For a long time, Windows had no way to control renders that spawned multiple
processes, something that Unix has had for decades.
RUSH on Windows 2000 uses Job Objects to kill processes when jobs are dumped
or frames are requeued, to make sure processes aren't left behind.
Some customers had noticed in previous releases of rush that on Windows
machines, sometimes renders like 'mayabatach' would be left behind after a
job was dumped. These could sometimes build up, showing the following undesireable
'leftover render process' showing up in the task manager:
The new use of Job Objects in 102.31p should prevent this completely.
