Debugger.addLineBreakpoint is setting sending blocking command to browser in AWT thread. Should probably use callback instead.
9b91c01c3b76 It is strange that it should take 5 seconds for your browser to respond to "addBreakpoint" command. I find communication with Chrome *instant* - as fast as embedded WebView. Could you keep an eye on this please and report back if your browser gets frequently slow. If it would help I can log time in WebKit Output window.
