FWIW I sometimes found that if an error occured somewhere, even 
an incorrect use of an undefined value, it screwed up mod perl's 
subroutine wrapper caching and caused the handler to run again. 
So you could be seeing the results of the second or third time 
the handler was hit. If you have warnings and strict on, hunt 
them all down, explicitly set empty string where it might be 
undefined etc, and see if it still happens.
