Comment (by cypherpunks):

 Attached simple solution for case of nodelist_map. It should be fast
 enough, if that working solution actually (can it leads to false
 positive?). Probably need to warn only without crash by assert, but broken
 could be danger. And no general solution for plan B for every hashtables,
 this one could be fixed by using the_nodelist->nodes to iterate over
 actual list to recreate HT. On the other hand it's not task for Tor to fix
 memory failures or do some workarounds for that case.
