First patch made memory allocations less aggressive. Second patch removed
runtime memory allocations completely, and relied solely on pre-allocated
pages. So, 2.4.9 VM goes south under intense memory allocation storms.

Hank, if it isn't too inconvenient, can you test unmodified loop-AES-v1.4d
with kernels 2.4.9-ac10 (not the newer -ac15) and 2.4.10aa1, both of which
have different VM than 2.4.9. Patches are here:
