perldoc LWP::UserAgent:

          By default the library uses alarm() to implement timeouts,
          dying if the timeout occurs...

	...

          $ua->timeout([$secs])
              Get/set the timeout value in seconds. The default
              timeout() value is 180 seconds, i.e. 3 minutes.


so when LWP does an alarm(180), that replaces your alarm 10.
