+TODOs:
+* symlink following behavior, trailing slash behavior (closely related to
+  symlinks) in cap-std isnt ready yet.
+* path_filestat_set_times, fd_filestat_set_times: no way to set times of a
+  path or for a Dir
+* File::set_fdflags is unimplemented, File::get_fdflags is lying - these are
+  fcntl on unix, reopenfile / ?? on windows. Not implemented in system-interface yet.
+* async scheduling!
