That wiki documentation is from the old spidermonkey js module not the new
v8 one.

I believe that putting a very large number will not cause any problems as
the data read cannot exceed the total bytes in the file so it should not be
a problem.
You can always do an append loop.  Its usually a good practice to have a
precise max size to read because what if the file was accidentally 2gb.
