+     *
+     * A file is said to be *valid* if the following conditions hold:

+     * V1. The "closed" and "curr" fields are correct:
+     *
+     * f.closed == closed(f) f.curr == curr(f)

+     *
+     * f.lo <= f.curr <= f.hi
+     *
+     * V3. Any (possibly) unflushed characters are stored in "f.buff":
+     *

+     *

+     * disk(f)[i])
+     *
+     * V5. "f.dirty" is true iff the buffer contains bytes that should be
+     * flushed to the file; by V3 and V4, only part of the buffer can be dirty.

+     * f.dirty == (exists i in [f.lo, f.curr): c(f)[i] != f.buff[i - f.lo])
