Another leak: tls_new_client_session

>  I’ll double-check that the sockets are cleaned up on exit.

Hi Alan,

I've uploaded a new log, valgrind-25k-tidc-nonstop.out, to the same location as before. 

This run used 25K tidc requests without a break. Between 9:26 and 17:34, RSS increased by around 3MB. That's roughly what I guess you'd expect if the sockets are reused all the time. I've now restarted the loop with a 15 second delay between results to let the server print the below before the next request kicks in again:

(159) Finished request
Waking up in 0.2 seconds.
Closing TLS socket from client port 48045
(0) >>> TLS 1.0 Alert [length 0002], warning close_notify 
Client has closed connection
Waking up in 0.2 seconds.
Waking up in 1.7 seconds.
 ... shutting down socket auth from client (127.0.0.1, 48045) -> (*, 2083, virtual-server=abfab-idp)
(159) <done>: Cleaning up request packet ID 0 with timestamp +342
Waking up in 2.9 seconds.
... cleaning up socket auth from client (127.0.0.1, 48045) -> (*, 2083, virtual-server=abfab-idp)
Ready to process requests

Between 17:34 and 17:40, using the --trace-origins=yes setting in valgrind, RSS grew from 265220 to 290064... Dunno if this is valgrind specifically that's blowing up memory usage so spectacularly, but the trend I'm seeing every time I do the ps check is similar to what we've seen before.

I'll check again later (I'm heading home now), and keep you in the loop.
