# Overflow table

The overflow table is the area that contains a list of
unused frames.

The overflow table is handled as a B-tree, rather than
as a finite set of overflow table entries. It is possible to set a *reserve* block of overflow, in case the system runs out
of disk. The overflow table can be rebuilt if it should become necessary.
