Btw, the v$sort_usage & v$tempseg_usage have "lied" for me before (due bugs or anomalies). If you're just interested in how much free space there's available for you then use v$temp_extent_pool...

The temporary extents are reused whenever needed. If you are ever concerned about current usage of the temp tablespace you can look at v$sort_usage.
