The simple answer is to make the buffer used to store the information a 
per task object.  The two complicated cases are exceptions in accept 
statements where you might need to create two copies of the information, 
and when an exception is raised in an exception handler.  If you want to 
"deal with" the second case, the per task data needs to be a stack or 
linked list.
