You should look at
CCodeGenerator>>collectInlineList

to understand why your code does not get inlined.

A long time ago I wrote up a change set to force inline of methods I  
thought were safe, but violated the rules, see
http://www.smalltalkconsulting.com/papers/tipsAndThoughts/source/ 
ForceInline-JMM.cs
Since this example is 5 years old, I'd expect it might require some  
changes. A little bit of debugging should show you
why the inliner is not doing the inlining.

Lastly since you are fiddling with slang, you should be aware if that  
if you have a instance variable, and if that instance variable
is used in methods that fold via inlining into a single C routine the  
global variable will become a c routine scoped variable. This
optimization was used to improve the garbage collector since the mark  
logic is folded into a single routine but had used instance vars for
recording state across multiple methods in ObjectMemory. If you do not  
wish this behavior you code up an accessor, then it will resort back to  
a global var.
