> The {{Context}} class has a {{clear}} method which is called. During the
> method, various files are deleted and in-memory maps are cleared. I would
> like to propose that we clear out an additional in-memory map structure that
> may contain a lot of data so that it can be GC'ed asap. This map contains
> mapping of "File Path"->"Content Summary". For a query with a large file
> set, this can be quite large.
