charm <anything> takes seconds to return

[Andreas Hasenack]

Why does the charm command take *seconds* for *any* command, even invalid ones? Here are some amazing examples:

andreas@nsn7:~$ time charm --help > /dev/null

real 0m2.879s
user 0m9.252s
sys 0m1.068s

andreas@nsn7:~$ time charm andreas was here
ERROR unrecognized command: charm andreas

real 0m2.718s
user 0m9.408s
sys 0m1.008s
