 tor stops working on slow connections for no reasons. it is unusable at
 all in countries with slow connections.

 how to get this bug:
 1. connect to internet using slow connection ( <150kbit/s, 200ms+ latency)
 2. start torbrowser. it connects fast, no problems.
 3. start browsing cp websites or dark markets. everything works.
 4. now go to kitchen, cook and eat some food, leave PC running.
 5. after 10-50 minutes, go back to your PC.
 6. click something on TorBrowser, a link. DOESN'T WORK. when I click link
 there is zero network activity, so Tor doesn't even try to request it!!!!
 but when I look tor.exe actually is connected to tor entry node with
 status Established. but nothing is sent or received when you click in
 TorBrowser (or if you try to use 127.0.0.1:9150 with other application, so
 it's not a TorBrowser bug).
 7. while Tor doesn't work at all, clearnet works perfectly with low
 latency.
 8. now I kill tor.exe external TCP connections (read again. I am not
 killing process, just it's external connections).
 9. tor.exe instantly reconnects to those TCP connections. But when I click
 something in TorBrowser there is zero network activity.
 10. I repeat step 9 again. tor.exe reconnects again (but to different
 entry node?) and it INSTANTLY works again. I can click links on TorBrowser
 and they load.
 11. After some minutes pass, go back to step 5.

 In steps 8-10, instead of killing TOR tcp connections you can also kill
 tor.exe to start working again. TorBrowser will restart it and it will
 work.
