// Remark: We cannot use the RemoteLoader directly from this AppDomain.
// csUnit v2.5 contains a bug in its detection of the NUnitAdapter. It tries
// to enumerate ALL types in ALL assemblies that are loaded in the AppDomain.
// Bad news for us because some of these types derived from other types in
// assemblies that cannot be loaded (eg. VisualStudio APIs).
// So csUnit promptly blows up. The workaround is to create our own AppDomain.
// We cannot use the csUnit Loader because it does things like report
// events asynchronously and possibly out of order or even in parallel. -- Jeff.
