can we make this launch when API is being used for the first time instead? same
goes for process->webproxy_thread(). Most of the users won't really have this
running anyway.

it is possible but in this case I need to either merge this CL with private
JSAPI CL into single CL, or just not to launch proxy in this CL at all.

launching webproxy is on demand now.
Idle webproxy thread is still started on startup.
