Ok, this is another story:  You are not looking for a least-effort solution just 
for your notebook.  Instead you want to contribute to the LMKL community 
solutions how to run current kernel versions under extremly tight memory 
limitations like with your notebook, right?  If so:  This is highly appreciated,
thank you!  I will interestingly read your findings :)
