+
+Currently working on:
+
+-- Spider script and module (within http library).
+
+-- Update NSE Book Implementation Section.
+
+-- Review and Improve NSE Nsock Library.
+     o Move away from C pointer references and allocation over to Lua.
+       If a function ends in error, all the userdata will be collected.
+       We would otherwise need to use pcalls everywhere to clean up
+       and free malloc()'d memory.
+     o Use thread calling nsock_loop (or currently running thread)
+       for restoring waiting threads to the running queue.
+       Making a function call on a yielded thread is a hack and
+       could cause problems in the future.
+     o Get rid of the static nsock_pool and use a dynamically allocated
+       structure on a per-host-group basis.
+
+-- NSE Debugger. Look at Diman's implementation:
+   http://seclists.org/nmap-dev/2008/q1/0228.html
+   http://www.keplerproject.org/remdebug/
+
+-- Merge utility functions into a single source file (e.g. table_length
+   and all debug functions). Is there a simple way to define a DEBUG flag
+   during compilation for the inclusion of the debug functions?
+
+-- Look into moving Packet Module to C.
+
+===
+
+Maybe:
+
+-- [MAYBE] Review NSE Nsock Socket Allocation:
+    o Dynamically increase socket slots if nothing has been done
+      in the last ~5 seconds. Also decrease once traffic is working again.
+      This resolves any sort of socket deadlock.
+
+-- [MAYBE] Deadlock identification and correction:
+    o Add detection for deadlocks and print which threads are involved.
+    o use above results to make a strategy for automatic deadlock resolution.
+
+===
+
+Done:
+
+-- Added boolean operator patch.
+
+-- Update NSE --script section (book) to include Boolean operators.
+
+-- Fix ceil for runlevels.
+
+-- Solve Brandon's Segfault for thread's sockets and close them when
+   the thread ends.
+
+-- Change the error on finding the name of a nonexistent file in script.db
+   into a non-fatal warning.
+
+-- Correct nsock_connect to unlock the socket slot if the connection fails.
+
+-- Remove packet.hextobin and packet.bintohex. Fix scripts that used them
+   to instead use bin.(un)pack.
+
+-- Commit --script-args patch and update the relevant section in the book.
+
+-- Deadlock identification and correction:
+    o Release mutexes upon script death.
+
+-- Review NSE Nsock Socket Allocation:
+    o Release socket locks on connection failure or timeout.
+    o Track active sockets in the nsock library and don't rely on
+      garbage collection for reallocation.
+
+-- HTTP Caching:
+    o Add ability to use a proxy to http.lua.
+    o Test http.lua performance using local caching proxy.
+    o Implement a cache in http.lua.
