Writing an [@include] directive

We have to write our own [@include] directive and I'm having problems.

The reason we need to do this is that each file we include needs to have 
its own datamodel, and not necessarily use the parent datamodel. We've 
also got to bypass the default template loading and template caching code.

I'm running into problems. If I try to fetch and process an external 
template from within a TemplateDirectiveModel, it fails to process more 
than one @include in a file. I'm having a hard time tracing the problem, 
but I suspect it's because the Environment is shared between the parent 
template and the included template. Environment is stored in a static 
thread local variable. This is just a guess.

If I put env.include(myIncludedTemplate) within the body of the 
TemplateDirectiveModel it works, but it makes it hard to swap datamodels.

Any thoughts or insight would be appreciated.
