to many user.warn kernel about alt-f

[GoogleCodeExporter]

This used to be a "frequent" warning, when there are many memory-demanding apps 
running.

I remember researching this, and the outcome was that is was a inocuos warning 
message.
There was a patch to avoid the kernel spitting the warning, but it was not 
accepted for inclusion.

I hope that the move to a more recent kernel, and a different memory allocator 
(SLUB instead of SLAB),
will make this vanish for ever.
But the main kernel developers are not very worried with low memory equipped 
computers (embedded), so it is not guaranteed the issue will disappears.

For future reference, I enclose a log of it when testing Transmission-2.80 
during heavy downloading.
In this case, the constant flood of new packets from different sources, with 
long TTL, should be the cause of the warning.
In other cases, such as running Python or PHP based apps, the huge code size 
requirement should be the reason.

Not closing just for future reference against the new kernel, but no action 
will be taken.
