seems ok, but I'm getting python test fail:
$ sudo ./perf test python -v
19: 'import perf' in python :

python usage test: "echo "import sys ; sys.path.append('python');

Traceback (most recent call last):

ImportError: python/perf.so: undefined symbol: hashmap__free
test child finished with -1
---- end ----
