We have had 'opportunities' when deleting users in production - sometimes jobs stop working.  
I understand that when a user is deleted, all objects referencing that user then are directed to an artificial account 'user unknown'.

But why would the jobs stop working?  I am fairly certain (not 100% tested) that these users are NOT defined in LOGIN or CONNection objects.
