           Summary: Web Inspector: [Chromium] Detailed heap snapshots
                    window becomes unresponsive if several long-running

          Platform: All

Consider the following scenario:
 - in the Dominators view, I have revealed all of the nodes;
 - now I'm clicking actively on column headers;
 - result: visually nothing happens, worker is overloaded, user confused;
 - only after some significant time (after worker has finished processing), the picture changes.

It should make sense to divide operations in batches, so worker can provide feedback and interrupt them if needed (e.g. if I'm changing sorting order before the worker has finished with sorting, it's better to interrupt the current sorting and start the new one).
