+1. The potential for bugs from failing to account for this within
signal handlers seems like a concern. I think that every process
should use the process latch, except for the archiver which uses a
local latch because it pointedly does not touch shared memory. I think
I wrote a comment that made it into the latch header comments
encouraging this, but never saw to it that it was universally adhered
