Make it go slower or force it to read *some* data at least. Interactively
there's plenty of time for data to arrive for read_very_eager() to read.
When run as a batch your computer tries to read and continue before any
data's been returned from google.
Hence, try using read_some() instead of read_very_eager().
Aside: If you want to interact with a mail server there's probably better
modules to be using than the telnet module.
