The hard limit on VAXen is 24MB of data. This is because the page table
design on VAX consumes an incredible amount of memory, so increasing it
will steal much static allocated memory. Note that traditional BSD on VAX
had a default data size on 6MB and a max on 16MB.

I have some ideas on how to decrease the amount of memory used by page
tables, but it will be far away in the future before this gets done.
