Comment (by cypherpunks):

 Good news. With hibernation we have: before
 {{{
 [10-07 19:14:15] Torbutton INFO: controlPort >> 650 STREAM 901 CLOSED 192
 5.8.6.1:443 REASON=DONE
 [10-07 19:14:40] Torbutton INFO: controlPort >> 650 STREAM 898 CLOSED 192
 5.8.6.1:443 REASON=DONE
 ...
 }}}
 ~20 streams. Streams of the closed tab are closing for ~30 seconds. After
 hibernation
 {{{
 [10-08 00:21:39] Torbutton INFO: controlPort >> 650 STREAM 884 CLOSED 192
 5.8.6.1:443 REASON=DONE
 ...
 }}}
 ~30 streams. And for each of those we have
 {{{

 kist_scheduler_schedule: Non-fatal assertion !((diff < 0)) failed. (Future
 instances of this warning will be silenced.) (on Tor 0.3.2.1-alpha )
