+ <listitem>
+ <para>The x86 native code generator has been reworked
+ considerably, and now works reliably. Using the NCG rather

+ intensive programs).</para>

+ exception.</para>
+ </listitem>
+
+ <listitem>
+ <para>If a thread is about to be garbage collected, because it
+ is waiting on an <literal>MVar</literal> that no other thread
