When datafiles are not released after dropping a tablespace then again lsof
is useful for identifying which process still holds the files open.
I've experienced a similar case in Oracle 9.2 on Solaris, it turned out that
the idle job queue processes still had the files open even after tablespace
was dropped. As I did not want to bounce the instance just because of that,
I set job_queue_processes = 0, waited until the processes died (and the
files were released) and set job_queue_processes back to original again.

As Ken mentioned, I have also seen this happening on IBM-AIX (Oracle 10g R2)
when I dropped a huge undo tablespace. We had to bounce the instance to
reclaim the space.
