Unloading of assemblies when exiting PIE

[dagillespie]

When exiting PIE mode when using external dependencies (eg as in #108), the application hangs and the following warning and error message appears:

LogUnrealCLR: Warning: UnrealCLR::Module::Log: Unloading of assemblies took more time than expected. Trying to unload assemblies to the next breakpoint... LogUnrealCLR: Error: UnrealCLR::Module::Log: Unloading of assemblies was failed! This might be caused by running threads, strong GC handles, or by other sources that prevent cooperative unloading.

A simple example that causes this is referencing NewtonSoft. Is there a way to resolve this?

If 3rd-party dependencies don't support unloadability with graceful unloading of resources, then developers should debug what causing this and work on that. More can be found here.
