Add " << endl" or " << flush" to the end of this statement.  IOStreams 
will buffer output otherwise, making it difficult to determine which 
order things actually happen in.

Add a cout statement in here (again, with a flush or newline).

Add one after this, too.

Do all that and try it again.  It may be that things are not happening 
in the order you think they are.
