Though this is just an educated guess, reading Anatoly's note and
Amaury's response leads me to think that Anatoly might be expecting
the execfile() function to work more or less like the exec* system
calls on Unix systems.  Execfile() is more akin to the import
statement than the fork/exec paradigm.
