'deleted' process in 2012 Mini hogging CPU

Anybody know what ‘deleted’ as a process name in Activity Monitor is doing? This process is routinely burning 50% to 100% CPU, according to Activity Monitor.

Mac Mini 2012, quad-core i7, 16 GB RAM. Running 10.15.4.

Looks like it has something to do with “CacheDelete” (some kind of purging of space in macOS?). A few years ago there were several conversations about it related to iStat Menus.

Might want to do full bootable clone and then update to macOS 10.15.7, to see how it works.
