But that's what you need to change. Think of it as the maximum amount  
of time a plugin is allowed to run if the plugin doesn't terminate  
itself within a reasonable amount of time. Misbehaving plugins are  
just the most common reason to hit this timeout. It should be set  
higher than the longest expected running time for any of your plugins.

Not necessarily. Only if your other plugins are badly behaved and  
don't terminate themselves in a timely manner. Mine is typically set  
to 60 seconds as I have some long running checks as well.
