It is a patch you apply on stock Python and you get a new configure
option: "--with-dtrace". If you compile Python with that flag, you get
a python interpreter with dtrace probes on it.

My plan is to (in the future) use that module to create new probes on
the fly, like
<http://chrisa.github.io/blog/2011/12/04/libusdt-runtime-dtrace-providers/>,
and to export functions to communicate data to dtrace scripts, if running.

That is, this module is currently a shell I plan to fill.
