	I see....if its so then yes there not really no much you could do....i guess 
then the best you can do is print a message with something like qFatal and 
exit if you cant continue without that allocation.....

	Maybe try to prevent crashes about memory failures would be a good idea like 
some said in other messages....checking a low limit or something....but yes 
to define this "low limit" would be difficult.....i guess we'll sitck with 
the cores files :):).......

	thanks all for your answers....

	Cheers...
