<p class="MsoNormal">This is a small fix for an issue on Windows
where NMT tries to track a free from a static destructor and
ends up hanging on acquiring the ThreadCritical lock. The fix
is to make sure we shut down NMT before the VM exits and then
to not track malloc/free when NMT is shutting down. Zhengyu is
working on a rewrite of the NMT feature where this won’t be an
issue, so this is a temporary workaround until then.<o:p></o:p></p>
