                            <comment id="1176087" author="scotthernandez" created="Wed, 17 Feb 2016 18:44:04 +0000"  >&lt;p&gt;One option for doing this is:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;check for dead sockets via polling for invalid socket file handles
	&lt;ul&gt;
		&lt;li&gt;poll on all socket file handles for health&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;get CurOp by dead socket address and kill (mark isKilled:true) where appropriate&lt;/li&gt;
&lt;/ol&gt;

Lots of edge cases:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;map/reduce
	&lt;ul&gt;
		&lt;li&gt;inline: can abort&lt;/li&gt;
		&lt;li&gt;to a named collection: cannot abort&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;commands that write things cannot abort&lt;/li&gt;
	&lt;li&gt;commands like count can&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;etc...&lt;/p&gt;</comment>
