------------------------------+--------------------------------
 While gk is waiting (for something?) in #12426, Tor needs its security
 mitigations to be corrected according to
 https://blogs.microsoft.com/microsoftsecure/2009/08/06/setting-sdl-memory-
 related-requirements-before-your-application-starts/ before the release.
 So, adding
 {{{
   HeapSetInformation(NULL, HeapEnableTerminationOnCorruption, NULL, 0);
 }}}
 after
 https://gitweb.torproject.org/tor.git/tree/src/or/main.c?h=release-0.3.0#n3570
 and changing
 {{{
     if (setdeppolicy) setdeppolicy(1); /* PROCESS_DEP_ENABLE */
 }}}
 with
 {{{
     if (setdeppolicy) setdeppolicy(3); /* PROCESS_DEP_ENABLE |
 PROCESS_DEP_DISABLE_ATL_THUNK_EMULATION */
 }}}
 will do the trick.
