Thanks. The approach that worked best by far was to load just NewCompilerLoader, then do:
NewCompilerLoader new loadPackages.
Then to correct syntax errors as they came up. The first error that wasn't a simple extra full-stop halted the recompilation process (because I couldn't fix it), but enabling the options mentioned meant that blocks are now fully reentrant. Excellent!

You can find it on squeaksource.

You first need to load AST NewParser RefactoringEgine and SmaccRuntime.
In other to load them all you could use the NewCompilerLoader
availible one the NewCompiler squeaksource repository.
Simply invoke:
NewCompilerLoader new loadPackage.
This will recompile the complete image using the NewCompiler.
To avoid the recompilation you can look at the loadPackage method.
You could also load the NewCompiler throw the Universe browser.
After loading the compiler you have 2 way to compile code.
1. Use the NewCompiler but don't make full block closure. (Preference
browser section compile #compileUseNewCompiler)
In this mode the block still remain the same and temp are share
among the home context. That the reason why you could not invoke
recursively a block.
2. Enable the block closure. (Preference browser section compile
#compileBlocksAsClosures)
With this preference the block while be transform in full block
closure. You could then recursively
invoke a block. Block while then create a environment to store temps
whenever is needed.
