Comment (by arma):

 Replying to [comment:7 asn]:
 > Sebastian points out that this `MAX_DL_TO_DELAY` delay functionality
 might also be performed by dirservers which makes the problem worse, since
 it means that dirservers will wait even longer before they get to 100%
 mds.

 That {{{n_downloadable >= MAX_DL_TO_DELAY}}} should only be checked if
 {{{!directory_fetches_dir_info_early()}}}.

 And in theory (there might be bugs), dir mirrors fetch dir info early.
