            <title>[SERVER-5651] Better implementation of Windows server shutdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-5651</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, StopMongoProgram() in shell_utils_launcher.cpp sends a SIGTERM on Linux, which shuts down the database cleanly.&lt;br/&gt;
On Windows, it actually connects to the database and attempts to issue a shutdown command. This can fail in a bunch of ways, and when that happens the shell calls TerminateProcess(), which shuts down the server uncleanly.  This becomes a problem in unit tests where we need to be able to shut down the server cleanly and start it up again.&lt;/p&gt;

&lt;p&gt;One way to improve this situation is to use Events.  These can have the same semantics as UNIX signals; the main difference is that on Windows, you need to explicitly set up a listener ahead of time.&lt;/p&gt;

&lt;p&gt;So in mongod, we will have a new thread that just calls CreateEvent() and then blocks in WaitForSingleObject().  After it unblocks, it simply calls dbexit().&lt;/p&gt;

&lt;p&gt;In the shell, in the implementation of stopMongoProgram(), it will call OpenEvent() to open the same event that the mongod created and then call SetEvent() to signal it.&lt;/p&gt;</description>
