I'd guess this is somehow related to the fact that removing a directory flushes the nami cache for things related to that directory's parent. This probably results in the kernel getcwd failing and it falling back to the userland getcwd code, which needs to read and stat every directory above you in the filesystem tree. Do you have a directory further up your path that isn't readable/statable? David.
