2	n/a	Input for test_profile.py and test_cprofile.py.

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