Truncating a table while it is being accessed by a query

This is a follow-up to a question that I posted some time ago.
The environment was Oracle 8.1.7.4 running on Solaris.
- We had a data warehouse with an ETL process which ran every hour and took
long enough that it ran constantly.
- Some of the ETL steps were truncating tables.
- Reports were failing intermittently with Ora-1410 (invalid rowid).
Through analysis of trace files I was able to demonstrate that the Ora-1410
errors only occurred when one of the tables being accessed by the report query
was truncated while the query was running.
Now my question is: Shouldn't Oracle be preventing the truncate operation
while another process was querying the table?
If not, isn't this a bug?
Thanks,
Peter Schauss
