<h1 class="faldoc_title">Threading module and VM Interruption protocol </h1>
<p class="faldoc_text">Interruptible operations will raise an InterruptedError if they receive an asynchronous interruption request from another thread while ingaged in a lengthy wait. </p>
<p class="faldoc_text">The Thread.wait method conforms to the VM Interruption protocol, along with other operations that are declared by the core module or by other extensions. Other interruptible operations are, currently: </p>
<ul>
<li>sleep function. </li><li>Stream.readAvailable </li><li>Stream.writeAvailable </li><li>Socket.readAvailable (at the moment, only on non-windows platforms) </li><li>Socket.writeAvailable (at the moment, only on non-windows platforms) </li>
</ul>
<p class="faldoc_text">We are working to extend the protocol to other VM-level and sustem level operations. </p>
<p class="faldoc_text">Other than coming from embedding applications, interruption requests can be generated by the Thread.stop method, that will send an asynchronous interruption request to the target thread. </p>
