Comment (by cypherpunks):

 During execution of that PoC my Tor Browser has crashed:
 {{{firefox.exe Exception Code: 0xc0000005 Address: 0x0000000000000000}}}
 (looks like null pointer dereference) on Win XP, but I still can continue
 execution and write this comment, but not to send it, because some
 networking-related thread is responsible for that exception, and every
 request ends up with
 {{{addons.update-checker        WARN    Request for
 https://www.eff.org/files/https-everywhere-eff-update-2048.rdf timed
 out}}}
