Sorry, folks - I have to recant. I was right the first time, oracle can be expected to waste space across N-1 extents - although it gets put on to the free list, of course.
Forget all the fancy traces, and the problems they give - if you have a 16 block extent size, and after the create table is complete you have 39 blocks on the segheader free list then you've left gaps in at least three extents.
