init and process control

I'm trying to wrap my head around process control in Unix... particularly init and how it fits in to the equation. Init is responsible for creating sessions by spawning instances of getty which calls login effectively creating sessions right? Why then can init belong to a session? If you ps jx 1, you will see init belongs to SID 1. Is SID 1 a pseudo session or just a bogus number added as a formality to the output of ps? I notice that a lot of other low level user processes belong to this special session. Could someone explain to me a little more about it? I've been googling all over the place today for a clearer understanding.

Thanks.

SSL_CTX_sess_set_cache_size(3SSL)				      OpenSSL					 SSL_CTX_sess_set_cache_size(3SSL)

NAME
SSL_CTX_sess_set_cache_size, SSL_CTX_sess_get_cache_size - manipulate session cache size SYNOPSIS
#include <openssl/ssl.h> long SSL_CTX_sess_set_cache_size(SSL_CTX *ctx, long t); long SSL_CTX_sess_get_cache_size(SSL_CTX *ctx); DESCRIPTION
SSL_CTX_sess_set_cache_size() sets the size of the internal session cache of context ctx to t. SSL_CTX_sess_get_cache_size() returns the currently valid session cache size. NOTES
The internal session cache size is SSL_SESSION_CACHE_MAX_SIZE_DEFAULT, currently 1024*20, so that up to 20000 sessions can be held. This size can be modified using the SSL_CTX_sess_set_cache_size() call. A special case is the size 0, which is used for unlimited size. When the maximum number of sessions is reached, no more new sessions are added to the cache. New space may be added by calling SSL_CTX_flush_sessions(3) to remove expired sessions. If the size of the session cache is reduced and more sessions are already in the session cache, old session will be removed at the next time a session shall be added. This removal is not synchronized with the expiration of sessions. RETURN VALUES
SSL_CTX_sess_set_cache_size() returns the previously valid size. SSL_CTX_sess_get_cache_size() returns the currently valid size. SEE ALSO
