  | In that case, I think we can interpret the "when" in the description
  | of the trap command literally except when 2.11 overrides it.

I think it should be interpreted just like its normal English usage,
as in:

	when I win the lottery I am going to buy a Ferrari
or
	I am going to buy a Ferrari when I win the lottery

(which both say the same thing).

It doesn't mean that the instant the lottery winnings arrive (tomorrow
please!) I will be at the luxury imported car dealers, rather it states
a pre-cpndition which will trigger an event which is to follow, sometime,
thereafter.

Thus
	When one of the correspomding conditions arrises (standards
	speak for "when a signal has been delivered") the argument
	action shall be read and executed...

is "sometime after a signal has been delvered, run the trap action".
