Even though you "control" the extents with USER, the
underlying concept is still usage of bits (typically 5
x blocksize, unless you already had MINIMUM EXTENT set
on the tspace before migration from dict=>lmt).
Thus, probably (assuming you don't want to use
uniform), an auto-allocate policy is best to limit the
possible "damage" from fragmenation (ie lost space)
