# Set of tests run by default if --pgo is specified.  The tests below were
# chosen based on the following criteria: either they exercise a commonly used
# C extension module or type, or they run some relatively typical Python code.
# Long running tests should be avoided because the PGO instrumented executable
# runs slowly.
