Best guesses:

* two separate queries are calling fetchrow_xxx() and getting each other's 
  results (the same reference is returned for each fetch).

* if you're running identical queries then theres's a chance that you're
  getting a collision in the prepare_cached method?  See the caveat emptor
  under "prepare_cached" in the DBI docs.
