Overlap of quick / merge sort on a second sort

[dlarocque]

When a merge or quick sort is started and then reset, they continue to the new shuffled array if another sort is started within ~5 seconds.
If another sort is called after the merge or quick sort after ~ 5 seconds since the reset, there are no issues.
The time between both sorts depends on the size of the array that was being sorted by the initial sort.
