  13. Tables are like sets: it is safe to insert and delete items while the table
  14. is being generated.  I don't know anywhere that this is explicitly mentioned.
  15. The possible combinations of legal operations are not generally enumerated,
  16. but it is reasonable for you to question whether this tricky case was
  17. considered during implementation.  It was.
