Pavel Tupitsyn commented on IGNITE-5730:
----------------------------------------
* {{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.
