I imagine that it held the critical locks briefly. I'm not endorsing
that approach, obviously, but apparently it more or less worked. It
was something that was used in rare cases, only when there was no
application-specific way to throttle writes, and only when the server
was in effect destabilized by writing out WAL too quickly.
