Heh, actually, I went searching my mail for when I had suggested that, 
and found that in fact I proposed this exact same method of using the 
unobserved xids array only back in October:

I had since forgotten all about, but now came up with the same idea 
again during review.

In the first reply in that thread you said that "The main problem is 
fatal errors that don't write abort records. By reusing the PROC entries 
we can keep those to a manageable limit". We're not worried about that 
anymore.
