I did not follow this thread, but I am pretty sure that
the condition you are using does not test correctly what
you want to find out.

Consider that Dir.glob returns an array of filename strings,
so that your condition *always* is true. (The first element
will never be an empty array).

A tiny change to the code will fix this...

Furthermore, assuming that you want to sleep as long as
the partial file *does* exists, you would also have to
use `while' instead of `until' (or invert the condition).

General tip: test the code snippet in isolation (using irb),
with files you create or delete manually.
