Sometimes there are old gcroots lingering arround from old builds that keep entire dependency trees from 2 years ago lingering arround
Cleaning those usually frees up gigabytes
An option for cleaning those with a timeout value specifiable in days
gc:
cleanAutoGcroots: true
cleanAutoGcrootsAfter: 20 # how many days to keep old auto-gcroots, before forcefully cleaning
with better naming or sth
