Wow, okay.

Unfortunately I am stuck with 2.7.x for the indefinite future, but since we
already maintain our own minor patches to the Python sources, I do not mind
adjusting this myself.

The path appends occur in the standard library "site" module.  You could

Excellent, I'll try this.  Modifying sys.path on the fly as Chris suggests
is possible as well, although the PYTHONPATH erasure is actually handled by
shell scripts which actually launch the programs.
