"""

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.
