[Vm-dev] browserPluginReturnIfNeeded

[John M McIntosh]

There is a vestige in the os-x vm for browser support, but it appears  
it was replaced by some logic that considers if the VM was a sub  
process of the parent process (the browser) to determine if the  
browser has gone away.  So it's not needed anymore, in fact the flag I  
set is never actually referenced anywhere anymore.

I had exploited it in the iPhone VM to check for memory leakage by  
terminating the VM process, but again not needed.

I'm sure I saw it used in the Hydra VM to exit each child VM process  
to the main dispatcher to deal with moving items between VMs, but I'm  
sure that
logic has changed.
