I would like to know what problem is solved by changing this to
any other value?

And then I would like to know why other potential solutions to
this problem were not considered, such as making the buffer size
dynamic and run-time selectable, perhaps with a size choosen
in a manner to avoid whatever problem you hit with the current
size.
