This is the real question I should have asked... what problem are you really trying to solve because while LMT uses an "extent" term, its definition and usage is very different from that of the traditional Oracle definition. The way the Area BitMap and SPAceManagement pages work, worrying about extent coalescing is a moot point. Which is one reason why some of those traditional tablespace qualifiers are ignored.
