using SemanticParserService with multiple threads ?

Hi,

In short - my question is whether it is possible to make the SemanticParserService parse multiple documents simultaneously using multiple threads ?
As I understand - it is using a single worker thread, which processes the requests one after the other.

backgound for my question:
In my project I load a large number of documents and parse all of them.
then I analyze all the ASTs and build a combined object model.
This is similar to what happens when you load a C# solution in the visual studio and get the class view of the entire solution.

The problem is that parsing all the documents takes a lot of time and I think that parsing them simultaneously (in multiple threads) might speed up things a litte (or maybe a lot...).

Thanks
