Actually, it might be OK to just match " is running " (or, likewise, without spaces).  I can't imagine the string "is running" appearing anywhere in the startup of a web server that *doesn't* indicate that the server, in fact, is running.

We probably don't want to just match "running" (i.e., it *is* possible that it says something like "The server is not running")...but matching "is running" will likely be more resistant to breakage in the future.
