So it wasn't the thread waiting for DirtyRegionQueue. It's hanging in
a thread at FindNodeForOffsetAction(ASTGenericVisitor).visit(IASTStatement)
line: 118.
I will look into this file, thanks for noticing my mistake. Also
since my first email I changed to code to use a ModificationCollector
but it still hangs here.
