[Bf-committers] signal.h

Hi,

While testing background rendering (from console) I noticed that ctrl+c  
doesnt stop Blender. The call to enable was commented out with this  
remark:

(Blender 1.8)
/* the SIGINT is commented out for python, then you can CTRL+C infinite  
loops */

In later Blender releases this comment and code was deleted. I prefer  
to have this back again. Is any Python guru here to tell me what Python  
has to do with it?

I've put it back at OSX and works fine. It should work for each  
platform, including Windows. I've adopted the old NeoGeo convention  
that it requires 2 CTRL+C's to kill Blender. The first one sets  
'G.afbreek' and prints "Press ^C again to kill Blender". The G.afbreek  
variable forces rendering to stop, and a few other routines like  
radiosity, metaballs, etc.

BTW: I've got old code here too that saved a .blend file at signal  
SIGSEGV...! I'll put that back later, needs careful testing.
