Note that write-behind makes your filesystem more fragile in the face
of crashes. Therefore, you should implement some manner to
periodically write all cached blocks to disk. If you have
-@code{timer_msleep()} from the first project working, this is an
+@code{timer_sleep()} from the first project working, this is an
excellent application for it.
Likewise, read-ahead is only really useful when done asynchronously.
