Well - you can't with WinPOV.  The point is having the choice - this is 
what Unix is all about.

Sure it could, but - as with various other features there has not been 
sufficient need to add such a feature to any editor i know of apparently.

If you think a bit about it - there is very rarely a need for actually 
pausing a render.  If you have another task that is more urgent the best 
way (apart from stopping the render) is to set priorities accordingly 
('renice').  The wish to actually completely suspend a render probably 
results from the common (but wrong) assumption that a computer is 
inefficient if occupied with several tasks simultaneously (in most cases 
it is more that those operating the computer have troubles with that ;-)).

That's of course one of the tougher choices (but not a bad one).
