Okay... so the reference count for the file handle drops to zero immediately
after execution of this instruction. Does this mean an explicit close is
being
done before the next instruction? If so then the two code snippets are
functionally
identical (with the second being much shorter). Also is the close
synchronous or
asynchronous?
