It is because of the foreign key. Inserting a child row will lock the
corresponding parent row, and if you insert multiple rows with different
parents in the same transaction, and do that in different concurrent
transactions but in different order of the parent rows, you can get a
deadlock. If you keep in mind that the parent row is locked on the
insert of a child row, you will figure out what's happening...
BTW, I don't think the "hackers" list is the right one for this kind of
question, better use the "general" list...
