# Test the interpreter (twice, once without .pyc files, once with)
+# In the past, we've had problems where bugs in the marshalling or
+# elsewhere caused bytecode read from .pyc files to behave differently
+# than bytecode generated directly from a .py source file. Sometimes
+# the bytecode read from a .pyc file had the bug, somtimes the directly
+# generated bytecode. This is sometimes a very shy bug needing a lot of
+# sample data.
