Subject: Possible infinite loop on buildfarm animals

Between approximately 11:05 UTC and 13:25 UTC today (15 Mar 2024),
the Postgres git repo contained a buggy test recipe that caused
an infinite loop that will eventually exhaust disk space.
If you have any animals that might have launched a test run on
HEAD in that interval, you might want to check up on them.
A manual kill of the process that's consuming 100% CPU should
be enough to get out of it.

Another idea to consider is to set the wait_timeout parameter
in your animals' configuration files, to put an upper bound
on the total elapsed time for a run.  By default that's
infinite, since it's really hard to select a one-size-fits-all
value ... but it's a good backstop if you don't mind picking
machine-specific limits.
