Sorry I was looking for AIM VII and/or reaim which are multiuser loads.
The results (2.6.20-rc1-mm1) for EXTREME, SPARSEMEM+VMEMMAP and
SPARSEMEM+VMEMMAP+your+patch are below. Note SPARSEMEM+VMEMMAP AIM VII
wasn't benchmarked to higher load limit because of my time constraints. 
The runs should be repeated more times.

Any difference between the three configurations looks insignificant and
within benchmark noise.

After tomorrow I'm on vacation until Jan 2.
