10g: parallel DML trigger race conditions?

are triggers executed in parallel for parallel DML? What happens, if the same record is updated _twice_ in a bulk update? Something like this:
forall i reloads.first..reloads.last

   update account set money = money + reloads(i).amount where account.id = reloads.acct_id;

Can it happen, that two "trigger before insert or update on account for each row" are executing in parallel for the same record?
- if acct_id = X is there multiple times in table reloads.

So they will find the same :old conditions. Or does oracle take care for sequential execution of trigger for same record?

• thanks!
