//! ### limitations
//!
//! - loom page size is fixed (16 KB), and must be a multiple of the
//! system page size. (can the size vary at runtime give south.bin's
//! reversed order? alternately, if system page size > ours, the fault
//! handler could dirty N pages at a time.)
//! - update atomicity is suspect: patch application must either
//! completely succeed or leave on-disk segments intact. unapplied
//! patches can be discarded (triggering event replay), but once
//! patch application begins it must succeed.
//! may require integration into the overall signal-handling regime.
