Add REHASH SSLD (admins only) that starts new sslds and marks the existing ones as inactive until all their clients disconnect. Very useful whenever the SSL library has a vulnerability because new connections can use a new version of the library without disconnecting existing clients/servers. Add STATS S (admins only) to list ssld processes, status, and client count.
