<p>Interruptible operations will raise an InterruptedError if they receive an asynchronous interruption request from another thread while ingaged in a lengthy wait. </p>
<p>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: <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>
<p>We are working to extend the protocol to other VM-level and sustem level operations. </p>
<p>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>
