+** Rules:
+**
+** - there is only one writer, but many readers
+** - prop_area.count will never decrease in value
+** - once allocated, a prop_info's name will not change
+** - once allocated, a prop_info's offset will not change
+** - reading a value requires the following steps
+**   1. serial = pi->serial
+**   2. if SERIAL_DIRTY(serial), wait*, then goto 1
+**   3. memcpy(local, pi->value, SERIAL_VALUE_LEN(serial) + 1)
+**   4. if pi->serial != serial, goto 2
+**
+** - writing a value requires the following steps
+**   1. pi->serial = pi->serial | 1
+**   2. memcpy(pi->value, local_value, value_len)
+**   3. pi->serial = (value_len << 24) | ((pi->serial + 1) & 0xffffff)
+**
+** Improvements:
+** - maintain the toc sorted by pi->name to allow lookup
+**   by binary search
