That would require a change to the NSPlugin API. The plugins themselves 
have to voluntarily stop what they are doing in a decent manner.

You cannot simply stop the process execution with SIGSTOP. That could lead 
to problems like timers not working, internal clock going out of sync, 
connections being dropped due to inactivity, etc.

Imagine you have a file-uploader plugin and you're uploading a large file 
over a slow connection. You want to keep working while it uploads, so you 
want the plugin to keep running in the background, while you switch to 
other tabs and other programs.
