[Pharo-dev] Re-purposing vm parameter 23 in Spur?

Hi All, right now vm parameter 23 is defined to be: 23 bytes of extra memory to reserve for VM buffers, plugins, etc. but is ignored by all the VMs (AFAIA). I would like to reinterpret this in Spur to be the minimum amount of headroom to make available on startup. I expect this is useful for really small platforms where one wants to control the ammount of free space on startup to be quite small. Given that the field is ignored I like putting it to a more useful purpose. Objections? -- best, Eliot
