Comment (by nickm):

 IIUC the default isolation options are:
 {{{
 #define ISO_DEFAULT
 (ISO_CLIENTADDR|ISO_SOCKSAUTH|ISO_SESSIONGRP|ISO_NYM_EPOCH)
 }}}

 So when I do 'git grep ISO_STREAM' I get:
 {{{
 src/or/connection_edge.c:  if ((iso & ISO_STREAM) &&
 src/or/directory.c:int iso_flags = anonymized_connection ? ISO_STREAM
 : ISO_SESSIONGRP;
 src/or/or.h:   * ISO_STREAM. */
 src/or/or.h:#define ISO_STREAM  (1u<<7)
 }}}

 Only one of these cases actually sets ISO_STREAM, in directory.c:
 {{{
 /* Anonymized tunneled connections can never share a circuit.
  * One-hop directory connections can share circuits with each other
  * but nothing else. */
 int iso_flags = anonymized_connection ? ISO_STREAM : ISO_SESSIONGRP;
 }}}
 but this only happens for directory connections, to ensure that they e.g.
 two service descriptor uploads can't share the same circuit.

 Convinced?  If not, can you remember what made it seem that ISO_STREAM was
 on by default?

Comment (by teor):

 Maybe I misread the code, or I misunderstood how ISO_STREAM works. Can
 someone check the ISO_STREAM default?

 circuits, right?

 Right. I think this would be a pretty big bug if so, and we'd want to fix
 it by fixing the bug, not by documenting it.
