Listing (recursively) the directories that we're about to copy is no bug, but a necessity.
But if kio_smb is doing kwallet lookups for every single file then that's a bug in kio_smb
(or possibly in kpasswdserver? not sure). Surely we should reuse the same password 
for the whole 'session' in the ioslave - more precisely, as long as the user+host doesn't
change, we don't need to look up the password every time.
