*(Edwin) Trace tree update - rebuilding pipeline state and cost of recompilation. Now handles merge notes. Optimizing it now off of previous branches. Constant recompiling is more than expected, so will continue to investigate.
*(Dave M) Introduce Joel Galenson,  
** Can turn trace trees on and it will pass the tests, but the performance is worse, so currently are leaving it off.
** Joel will be an intern working through August
** Pipelining is now starting to pay off!
** regexp tracing (generating method IL on the fly, fast access to string chars)
 
*(David A + Andreas) Explicit field initialization in constructors?
*(Andreas) Compartmentalizing nanojit for use by tracemonkey as well as TT
*(Andreas) Reorganize Interpreter.h/cpp? TraceMonitor/TraceRecorder split?  
** It was a small namespace change. Add a delete operator?  
*(Andreas) Register allocator discussion (loop-spanning register use, tree-spanning register use.)  
** Should we start a wiki page to track these items?  Or Bugzilla?  ACTION: Andreas will write something up and send out a link.
*(Moh) 13% performance for 13% size increase: space/speed tradeoff in configuring TT: https://bugzilla.mozilla.org/show_bug.cgi?id=442804
** Moving more filters (e.g., CSE) into nanojit
*(Jungwoo) Protection problem in Windows 2003 Server: https://bugzilla.mozilla.org/show_bug.cgi?id=442961
 
*(Mark) Wondering about ASC on TT.
** ACTION: Dan will touch base with Mark on this to assist.
