-----------------------------------------------------------------
* {{DomainUnload}} is not called in default domain. {{ProcessExit}} should be
used instead.
* When Ignite is started in a non-default AppDomain, we should use
{{DomainUnload}}. But we rely on {{UnmanagedTarget}} and {{UnmanagedContext}}
finalizers to clean up unmanaged objects, so we can't unload ignite.jni.dll
before everything is finalized. And finalizer order is undefined. Seems like
there is no reliable way to handle this.
Maybe we should not waste time on this and implement IGNITE-5343 instead, which
gets rid of {{ignite.jni.dll}} altogether.
