Running a debugger when developing the application is quite different
than running one at deployment time. When you deploy an application
and it crashes, it is helpful to know what happened before the
crash. AFAIK, no one uses a debugger at deployment time.

I guess that is the reason why airplanes have a black box and
not a debugger. :-)
