Thanks for the help!  Something like this should go into doc/testing.md

I found that running one value of the param at a time works best for me:

(cd $(hg root) && for size in 3 16 999 999999; do make test
TEST="micro:java.lang.ArrayFiddle"
MICRO="FORK=2;WARMUP_ITER=4;ITER=4;OPTIONS=-opi $size -p size=$size" |&
perl -ne 'print if /^Benchmark/ .. /^Finished running test/'; done)
