IMO it's not a good idea to let the IDE and the compiler share the same 
address space. Even if the compiler could reuse the data (files...), 
loaded into the IDE memory, the synchronized access can cost much runtime.

Since Lazarus already includes an parser, a built-in compiler should be 
feasable. But I'm not sure how far the FPC developers will support a 
threaded version of the compiler, that would integrate neatly into Lazarus.
