[mod_python] gdbm and reorganize...

What has this got to do with mod_python you might ask. Good question. I 
found that gdbm is faster that dbhash - the app won't be running on 
windows anyway...

 >>> db["a"] = "rune"
 >>> del db["a"]
 >>> db.reorganize()
 >>> db.close()

Anyone got any idea why reorganize() fails on a gdbm database created 
by Session.Dbmsession() ?
