+<p><!-- https://golang.org/issue/49759 -->
+  The <pre>windows/arm</pre> and <pre>windows/arm64</pre> ports now support
+  non-cooperative preemption, bringing that capability to all four Windows
+  ports, which should hopefully address subtle bugs encountered when calling
+  into Win32 functions that block for extended periods of time.
