Hmm.. While I normally like having this kind of "instant  
notification", I could see this as a very big problem for larger  
installations.  Most OS's are not so great at launching new tasks, and  
on a heavily loaded system that could easily be a number of tasks  
launched every second, each doing a lot of database queries.  Perhaps  
a different approach would be to have a field that can be set to show  
that the record(s) have been parsed into whatever standard CDR format  
you want.  This may or may not make more sense as a separate table  
with just a list of linkedid's that have been parsed.
