There was a problem hiding this comment.
Thank you @crepererum
In case anyone is interested, I drew a picture of the cycle:
┌───────────────────────┐
│ │
│ MemoryCatalogList │◀───┐
│ │ │
└───────────────────────┘ │
│ │
│ │
▼ │
┌────────────────────────────┐ │
│ │ │
│CatalogWithInformationSchema│──┘
│ │
└────────────────────────────┘
FWIW this was causing us trouble in IOx because our main object implements SchemaProvider and thus was kept around by this cycle
