I understand it.

But just imagine a situation in which the potential for double locking 
in a one-threaded environment is posiible.
It is not possible at all. But I see that when executing 
ServerSocket::doThis() sometimes method ServerSocket::slotDisconnected() 
is called asynchronously, so to speak. I.e. in the middle of 
ServerSocket::doThis() invoked ServerSocket::slotDisconnected(). How 
it's possible in one-threaded app?
