Three little enhancements/mini-bugs:
1) Adding the following lines to the "main part" of pdb.py 
gives it the ability to stay in pdb if the program crashes. 
Very handy!
 # Ensure that we end up in pdb if we crash
 def pdb_on_crash(type, value, tb):
 sys.__excepthook__(type, value, tb)
 post_mortem(tb)
 sys.excepthook = pdb_on_crash
2) There's also a problem in the last lines of pdb.py:
 # Insert script directory in front of module search path
 sys.path.insert(0, os.path.dirname(filename))
This leaves the directory path under which pdb.py was 
invoked in sys.path. This is a problem if pdb.py was 
invoked e.g. via a link a la /usr/pdb. This leads to the last 
and related suggestion.
3) It would be very convenient if a pyhon installation would 
also install a link /usr/pdb -> /usr/lib/python2.3/pdb.py. 
This provides for easy invocation and, for example, it's also 
the default command used by Emacs' pdb-mode.
