This code was originally written as part of parallel query effort, but it seems to have independent value, because if we make one decision about where to get a PGPROC when we allocate and then put it back on a different list at backend-exit time, bad things happen. This isn't just a theoretical risk; we fixed an actual problem of this type in commit e280c630a87e1b8325770c6073097d109d79a00f.
