Cristiano Giuffrida b4d6d9db26 Fix bug in IPC deadlock detection code. 
The old deadlock code was misplaced and unable to deal with asynchronous
IPC primitives (notify and senda) effectively. As an example, the following
sequence of messages allowed the deadlock detection code to
trigger a false positive:
1. A.notify(B)
2. A.receive(B)
3. B.receive(A)
1. B.notify(A)
The solution is to run the deadlock detection routine only when a process is
about to block in mini_send() or mini_receive().
