[Import-sig] imputil

[Thomas Heller]

imputil, which is now an official part of
python, changes the semantics of sys.path
as soon as importers are installed.

On the other hand, a quick and dirty search
finds at least these files in the standard library
where it is assumed that sys.path is a list of strings:

linecache.py, profile.py, pdb.py, pyclbr.py

Should imputil be fixed to install the ImportManager
in a different way (not installing the importers
into sys.path), or should the library be fixed?
