Note that it's currently not possible to inspect the trace/profile hooks 
from Python code, only from C, so that might be, um, interesting to implement.

Interesting; I'm not sure if I like it.

What does this do?  Oh, I get it.  The name's not very obvious.  I would've 
expected a more imperative name, something like 'with os.setcwd()' or 'with 
os.pushdir()'.

Yeah, again I would expect more verbish names, but these are at least 
easier to grasp than current_directory was.
