            <title>[SERVER-5819] Use FileAllocator on Windows</title>
                <link>https://jira.mongodb.org/browse/SERVER-5819</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Testing revealed occasional unexpected long delays (and retries) when calling FlushViewOfFile().  As a work around, we could simply allocate (and zero out) the files using the existing FileAllocator implementation.  Initial testing seems to indicate that this avoids any failures in FlushViewOfFile(), which would normally require retrying.&lt;/p&gt;</description>
