Algorithm~\ref{alg:heapObjectFreeOwn} shows how a free request is fulfilled if object ownership is turned on. Algorithm~\ref{alg:heapObjectFreeNoOwn} shows how the same free request is fulfilled without object ownership.

\begin{algorithm}
\caption{Dynamic object free at address A with object ownership}\label{alg:heapObjectFreeOwn}
\begin{algorithmic}[1]
\If {$\textit{A was mmap-ed}$}
        \State $\text{return A's dynamic memory to system using system call munmap}$
\Else
        \State $\text{B} \gets \textit{O's owner}$
        \If {$\textit{B is thread-local heap's bucket}$}
                \State $\text{push A to B's free-list}$
        \Else
                \State $\text{push A to B's away-list}$
        \EndIf
\EndIf
\end{algorithmic}
