This is definitely not a silly question.

As far as I know, these magic numbers values refer to the timeout value for
each operation. However, I also do not understand how to choose a value for
each function call. Generally, when I need to change some code, I just copy
and past the code block and maitain the magic numbers. I just have faith
they will keep working fine in my code :-)

It would be nice to hear some words about choosing these timeouts values (
unless this is a really silly question ).

Regards,

Loreno
