Hey, get this! [was: import from database]

[Steve Holden]

This is even stranger: it makes it if I import the module a second time:

import dbimp as dbimp
import sys

if __name__ == "__main__":
     dbimp.install()
     #k = sys.modules.keys()
     #k.sort()
     #for kk in k:
      #print kk
     #import bsddb.db
     import a.b.c.d
     import smtplib
     import ftplib
     import fileinput
     try:
         print "first import"
         import bsddb
     except:
         print "second import"
         import bsddb
     print "Done!"

$ python -i test.py

So it's clearly something pretty funky. It now "works" (for some value 
of "work" wiht both MySQL and sqlite. I hope I have this sorted out 
before PyCon ... I'm currently a bit confused!
