This is almost *exactly* what I thought: but:

Since C and D are not bridged before A and B get masqueraded, we'll end
up with this:

- C and D are unconnected.
- Masquerade (A, C) will connect the person A talks to (MOH for example)
to C.
- Masquerade (B, D) will connect the person B talks to (Person F for
example) to D.
- Bridging C and D will result in Person F hearing MOH.

If the bridge would also work on fresh, yet unconnected, channels, we
could have done the following:

- Allocate C and D
- Bridge C and D in a new thread
- Masquerade (C, A) -connect the Person C is talking to to A (which is
D) 
- Masquerade (D, B) -connect the Person D is talking to to B (which is
A, masqed as B)
- Voila, A and B talk.

Problem is: ast_bridge doesn't work on unconnected channels and returns
immediately.

I have almost no teeth left...
