Hi, The Cog virtual machine expose some very useful parameters. However, some of them are a bit obscure to me. For example, what are the following parameters? What do they mean? 46 size of machine code zone, in bytes 59 number of check event calls since startup (read-only) 60 number of stack page overflows since startup (read-only; Cog VMs only) 61 number of stack page divorces since startup (read-only; Cog VMs only) Is there a way to get access to the cache? How many caches does Cog has? I guess it has - a method call cache (associating (object,symbol) -> compiled method - a cache for the JIT-compiled methods right? Are there other cache? How can I access them? In particular to query about their fill.
