Firstly, are you actually calling test_binary_trees? If not, you're
just importing some modules, and defining a function, then exiting.
Secondly: os.system will run the binary_trees.py in a separate process,
invoking it via whatever is in the shebang line. That won't inherit
any of the jitlog settings you've done in this process (and if it's
#!/usr/bin/python, it could be CPython you're invoking).
Hope this is helpful
Dave
