Code that uses TaskQueue to hold stealable tasks has to allow for the fixed-size TaskQueue to overflow. This is often done using a separate per-thread overflow stack. Maintaining the TaskQueue and overflow stack separately is tedious and error prone; a TaskQueue with built-in overflow handling is needed.
