--- STATLITE
-  statlite(const char *filename, struct statlite *buf);
-  fstatlite(int fd, struct statlite *buf);
-  lstatlite(const char *filename, struct statlite *buf);
-
-  * file size, mtime are optionally not guaranteed to be correct
-  * mask field to specify which fields you need to be correct

--- READDIR+
-
-  struct dirent_plus *readdirplus(DIR *dirp);
-  int readdirplus_r(DIR *dirp, struct dirent_plus *entry, struct dirent_plus **result);
-  struct dirent_lite *readdirlite(DIR *dirp);
-  int readdirlite_r(DIR *dirp, struct dirent_lite *entry, struct dirent_lite **result);

-  * plus returns lstat
-  * lite returns lstatlite

--- lazy i/o integrity
-
-  FIXME: currently missing call to flag an Fd/file has lazy.  used to be O_LAZY on open, but no more.
-
-  * relax data coherency
-  * writes may not be visible until lazyio_propagate, fsync, close
-
-  lazyio_propagate(int fd, off_t offset, size_t count);
-   * my writes are safe
-
-  lazyio_synchronize(int fd, off_t offset, size_t count);
-   * i will see everyone else's propagated writes

--- read/write non-serial vectors
-
-  ssize_t readx(int fd, const struct iovec *iov, size_t iov_count, struct xtvec *xtv, size_t xtv_count);
-  ssize_t writex(int fd, const struct iovec *iov, size_t iov_count, struct xtvec *xtv, size_t xtv_count);

- * like readv/writev, but serial
