I don't get that impression at all!  From what I've seen, I've answered

In fact, it seems a better and better idea the more I answer the concerns.

Please explaing exactly why this is so, or give me pointers so I can read
the research papers explaining why this is so.

Could you please be more specific than "unmitigated pain"? 

Also, let's consider the "typical" piece of h/w that I think will be common
when I finish writing this code: An Alpha or Merced at >= 500 MHz
with at least 1/4 GB of DRAM and around 50 GB of disk.
