SubjectBenchmarking objrmap under memory pressure
UP Athlon 2100+ with 512Mb of RAM. Rebooted clean before each test
then did "make clean; make vmlinux; make clean". Then I timed a
"make -j 256 vmlinux" to get some testing under mem pressure.

I was trying to test the overhead of objrmap under memory pressure,
but it seems it's actually distinctly negative overhead - rather pleasing
really ;-)
