timeout restart in pexpect

[Pankaj]

I am using pexpect to automate some procedures.

My procedures are time cosuming, some messages coming out from that,
in failure cases it will not output anything.

So I would like to give small timeout value but when some message is
received, it should restart the timeout, similar like
"restart_timeout_upon_receive" in perl.

Is it possible in Python using pexpect ?
