No, timeout issues are "the target input didn't arrive in this timeframe".

All his commands are _local_.

Krishna: if you're blocking waiting for a pattern (eg "Password:") and it times 
out, even for big timeouts, then maybe the pattern is wrong. A command like 
"su" will prompt for a password and then wait indefinitely. If your prompt 
pattern is incorrect, you will wait indefinitely waiting for the pattern to 
show up, because it never will.

Run an interactive "su" and see if it matches your pattern.

And so on.
