\begin{description}
\item[\ref{fig:newact-block.1}] The user-level thread~$1$ is running onto
an activation~$A$ bounded to a processor.
\item[\ref{fig:newact-block.2}] The thread~$1$ makes a system call
blocking the activation~$A$. Another activation~$B$ is launched
which runs another user-level thread~$2$.
\item[\ref{fig:newact-block.3}] An interrupt occurs. The blocked
activation $A$ will be able to wake up (when requested by the
application).
\item[\ref{fig:newact-block.4}] The activation $B$ is used to send
the unblocking notice event with an upcall. The user thread
scheduler put the thread~$1$ in the ready-to-run thread queue.
\item[\ref{fig:newact-block.5}] When the user thread scheduler
wants to restart the unblocked thread, it saves the currently
running thread state and discard the current activation in
favor of the unblocked thread activation.
\end{description}
To limit the number of activations, unblocked activations are
rescheduled instead of new ones when a thread blocks (state
\ref{fig:newact-block.2}).
