Improve handling of post-load background jobs.

Browse Source 
Background tasks (source location zones sorting, reconstruction of
memory plot) are now started only after trace loading is finished.
Multithreaded sorting was previously impacting trace load times.

Only one thread is used to perform both jobs, one after another.
