I had already concluded that this would not be useful for the use cases I have at work. The running out of memory and the hard crash is what would stop me using this in production. For my day job I work on a service that forks slave processes to handle I/O transactions. There is a monitor process that manages the total memory of all slaves and shutdown and replaces slaves when they use too much memory. Typically there are 60 to 100 slaves with a core each to play with. The service runs 24x365. Barry
