Oracle-L: Large record count in fet$ for TEMP tablespace

When trying to select * from DBA_FREE_SPACE_COALESCED the query hangs. It also hangs when trying to calculate free space from the DBA_FREE_SPACE view. I looked in the sys.fet$ table and found that the TEMP tablespace has 21423 entries and I believe this is my problem.

Now for my questions.

Is coalescing the best solution for this problem?
Can I coalesce the tablespace without changing it to a permanent tablespace?
Is there a faster way to drop the exents then the alter tablespace coalesce command? I ran it for about 10 minutes and canceled it.
Is this normal and do I need to coalesce the TEMP tablespace on a regular basis to avoid this happening again?

Thanks,
CAJ
