I think it is a good monetdb practice to manage the memory monetd is allocated at the OS level.
Typically on Linux, you will have to use ulimit.
Don't know how (if) your Windows flavour can handle that, but AFAIK, this is the way to go.

MonetDB is a *main-memory* database.  It will basically keep as much in
