Please bring back:
// force lazy compilation of inspector related scripts
send(JSON.stringify({id: ++lastId, method: 'Runtime.evaluate', params:
{expression: ''}}));

It forces injected-script-source.js compilation, otherwise we'll measure not
only Debugger.paused event but injected-script-source.js compilation as well.

Whoops! Done
