Description

FilterFileSystem is incorrectly delegating deleteOnExit to the raw underlying fs. This is wrong, because each fs instance is intended to maintain its own pool of temp files. Worse yet, this means registering a file via ChRootedFileSystem#deleteOnExit will delete the file w/o the chroot path prepended!
