Logging events in Necko

Hi,

I just filed bug 801209: Logging events in Necko

The idea is that Chrome has a pretty good and detailed way of logging 
networking events.
It can be accessed from chrome://net-internals

The current logging system in firefox is completely functional, however, 
it does not have the same flexibility. One needs to set certain 
environment variables in order to enable it.

Any thoughts?
