+ *
+ * - PORTArenaPool (defined in secport.c): this "subclass" is always
+ *   heap-allocated and uses a (heap-allocated) lock to protect all accesses.
+ *   Use PORT_NewArena() and PORT_FreeArena() to create and destroy
+ *   PORTArenaPools.
+ *
+ * - PORTCheapArenaPool (defined here): this "subclass" can be stack-allocated
+ *   and does not use a lock to protect accesses. This makes it cheaper but
+ *   less general. It is best used for arena pools that (a) are hot, (b) have
+ *   lifetimes bounded within a single function, and (c) don't need locking.
+ *   Use PORT_InitArena() and PORT_DestroyArena() to initialize and finalize
+ *   PORTCheapArenaPools.
