Are you sure that he timeout is not being generated by nagios?

BTW - I really have to question the wisdom of what you seem to be trying
to do here. ISTM that a timeout is rather bad thing, and should be
critical. Now you may have a network where 10 seconds is not enogh for a
ping, but that really is a problem that you ought to fix. And to the
extent that you have to live with a ping still not coming back in 10
seconds, then I would think increasing the timeout is easier than
changing the code.

Is there some point I'm missing that motivates you to take this
approach?
