- Input for test_profile.py and test_cprofile.py.

- IMPORTANT: This stuff is touchy. If you modify anything above the
- test class you'll have to regenerate the stats by running the two
- test files.
-
- *ALL* NUMBERS in the expected output are relevant. If you change
- the formatting of pstats, please don't just regenerate the expected
- output without checking very carefully that not a single number has
- changed.
