How about UNDO tablespace in 9.2?
It gets created with "autoallocate", and there is no way to change it or
specify any parameters for undo segments.
Each segment extended as needed, and when shrinked deallocated some extents
not necessary the last, than allocate new extent.

You do get odd results. The last time I tested on
a clean tablespace, an initial of 65MB gave me
a consistent result which I recall as:
Extent 0 at 8MB
Extents 1 - 56 at 1MB each
Extent 57 at 8MB

case
when initial_extent < 1m then
case when extents < 16 then next = 64k,
when extents < 80 then next = 1m,
when extents < 200 then next = 8m,
else next = 64m
when initial_extent >= 1m then
case when extents < 64 then next = 1m,
when extents < 184 then next = 8m,
else next = 64m )
