Comment:

 I've tested dev at commit de86a70 which is where they were last merged.
 For reference, connection.c's md5sum at this point is
 8a928954d14790ed8f2a9d494d14ea58 (please verify).

 It falls down as follows:

 {{{

 15253 old router descriptors.

 If I uncomment in torrc the second ORPort line containing the IPv6 it does
 not fall down.
