Subject: Do not invoke ppworker script directory -- run it via -m option of python

 Invocation of script directly results in Python adding a directory containing
 the symlink-dereferenced path to the script into the path.  On Debian systems
 it would result in adding /usr/share/pyshared path to the sys.path breaking
 import of many modules.
