Example output is now:

Deserialization will reserve:
    830904 bytes per startup
    197152 bytes per context
Snapshot blob consists of:
    501348 bytes for startup
     66268 bytes for context
Creating snapshot took 59.413 ms

This way we can correctly attribute the numbers by parsing single lines.
