+152) Fix CSS references in the website documentation.
+ For many pages p_doc.css is specified twice using different paths.
+ Usually at least one works, but not all of them do and the
+ duplicated requests are pointless even if they don't end up with
+ a 404.
+
+153) Catch SIGINT and use it to close the listen socket, serve
+ remaining connections and shut down. This would allow higher
+ uptime and make testing more convenient.
+
+154) Underline links in docs and cgi pages. More precisely,
+ don't mess with the browser defaults for link underlining.
+
+155) The sig_handler() shouldn't call log_error().
+ While it isn't known to cause actual problems in normal operation,
+ it's technically incorrect and causes crashes when running in
+ valgrind.
+
+156) Reject socks requests with an explicit error message similar
+ to the one used for ftp. Motivation:

+
+158) Use a single thread to wait for new requests on reused client connections.
+ Currently the thread that handles the first request on a connection
+ stays responsible for the client connect until it gets closed.
+ In case of lots of idle connections lots of waiting threads are used.
+ While it's conceivable that this ineffiency is irrelevant from a
+ performance point of view, using a single thread should reduce Privoxy's
+ memory footprint a bit which may be noticeable in case of multi-user setups
+ with hundreds of idle connections.
