Public bug reported:
Binary package hint: python2.5
I was investigating why a task which spawned many very simple Python
scripts was taking a substantially time running on my Feisty
installation than on my Dapper installation, and I ran across the
installation of the "apport" hook. The functionality there is very
cool, and I appreciate it, but I removed it and saw these modules
imported with python -v:

This is a substantial and unnecessary overhead for a hook which will be
invoked only if the process exits with an error. While quite a few
Python programs import a huge number of modules, some are tuned to be as
conservative as possible about importing for performance reasons; that
should be respected by the system installation.
The functionality need not be lost, since sys.excepthook should instead
be set to a one-line function which, if apport were not yet imported,
imported it.
** Affects: python2.5 (Ubuntu)
