Buck Evan:

Without `--withmod-time`, the example in the docs crashes: http://pypy.readthedocs.org/en/latest/getting-started-dev.html#pyinteractive-py-options



```
$ python bin/pyinteractive.py --withmod-time -c "from test import pystone; pystone.main(10)"
...
Pystone(1.1) time for 10 passes = 0.220043
This machine benchmarks at 45.4457 pystones/second
```
