TeamCity SVNResourceChangeDispatcher.resourceChanged hangs Eclipse

I deleted some unused projects from my workspace (but not from file system) in Eclipse. Eclipse has now been hung by TeamCity SVNResourceChangeDispatcher.resourceChanged() for over 45 minutes, with the suspect threads below.(thread dumps attached)

What is it doing? And, perhaps it shouldn't!
