Good suggestion and I kind of like this name ;)
Gerhard, what do you think?

Here I think that idea (originally) was that heapsize specifies heapsize of the JVM,
but not the size of the store (because it is (almost) impossible to determine), so my
understanding is that these parameters (heapsize and freememory) should also
go into janitor configuration.

Agree.

heapsize and freememory also (see above)
