 * By-default, when dumping a unix socket, we should dump its peer
 * as well. Which in turn means, we should dump the task(s) that have
 * this peer opened.
 *
 * Sometimes, we can break this rule and dump only one end of the
 * unix sockets pair, and on restore time connect() this end back to
 * its peer.
 *
 * So, to resolve this situation we mark the peers we don't dump
 * as "external" and require the --ext-unix-sk option.
