+wasi_tests::directory_seek
+    - something weird about directory open rights / fdstat. need debug
+      impl of Caps to see about this
+wasi_tests::fd_flags_set
+    - set_fdflags is not implemented. test wanted to clear O_APPEND mode
+wasi_tests::fd_readdir

+    - fdstat.fs_flags is not populated correctly
+wasi_tests::path_link
+    - path_link is not implemented
+wasi_tests::path_rename
+    - path_rename is not implemented. we need to be able to downcast a dyn

+wasi_tests::path_rename_trailing_slashes
+    - path_rename is not implemented
+wasi_tests::path_symlink_trailing_slashes
