Comment (by cypherpunks):

 What key material is being considered as sensitive here? Is it only
 private keys, or does it also include ephemeral session keys and related
 information? It's important to determine what's in scope.

 Also, coredumps do not have to be an issue if Tor sets
 `prctl(PR_SET_DUMPABLE, 0)`.
