 == Stage 1 ==
-Integrate SpiderMonkey more closely with MMgc.
+Integrate SpiderMonkey and Mozilla DOM more closely with MMgc.  See the ActionMonkey Stage 1 tracking bug, {{bug|393023}}.  (Under "Depends on", you can see a list of bugs slated for stage 1.)
-* Get rid of js_GetGCThingFlags.  (Ed maybe)
+Stage 1 work includes:
-** The type bits: move to an MMgc page-level type tag.  (Note:  The cycle collector sneakily uses these, in <tt>nsXPConnect.cpp</tt>; it will be changed.)
-** The <code>GCF_LOCK</code> bit: mainly replaced by allowing MMgc to scan <code>rt-&gt;gcLocksHash</code>.  There is also a string optimization that uses this bit.  It's yet to be determined what to do about that.
+* {{bug|392883}} - Get rid of js_GetGCThingFlags.
-** The <code>GCF_MUTABLE</code> bit:  move into <code>JSString</code>.  (A patch against CVS trunk exists for this.)
+** The type bits: use the C++ vtable, maybe.  (Note:  The cycle collector sneakily uses these, in <tt>nsXPConnect.cpp</tt>; it will be changed.)
+** The <code>GCF_LOCK</code> bit: already gone in actionmonkey branch, mainly replaced by allowing MMgc to scan <code>rt-&gt;gcLocksHash</code>.
+** The <code>GCF_MUTABLE</code> bit:  move into <code>JSString</code>.  Already done in CVS trunk.
 ** The <code>GCF_SYSTEM</code> bit:  To be determined.
-* Drop weak roots, newborns, and local root scopes (if they're not already gone in stage 0).  These will be replaced by MMgc's conservative stack scanning.  (Ed has a patch for this already.)
+* {{bug|388622}} and {{bug|391676}} - Drop weak roots, newborns, and local root scopes (if they're not already gone in stage 0).  These will be replaced by MMgc's conservative stack scanning.
+* {{bug|393034}} - Start allocating Mozilla DOM objects using MMgc.
