The problem is FAR worse than arbitrary interleaving. You are
doing uncoordinated writes to a variable (the internal file
variable), so the program is erroneous. Arbitrary interleaving
is actually a very nice behavior, but a program crash due to
inconsistent data structures is not unexpected in this situation
(or at least should NOT be unexpected). If you want this kind
of interleaving, you need to provide a synchronizing agent
