Re:guard pages, bit masks, and so on: better (Score 1)

I really like the suggestion - you have something that is quite a discrete operation - you map a page of memory and then start a thread and do the operation and let it run in an almost sandbox. sounds really good for things like video decoding or packet protocol decoding where sanity checking does become expensive (ie video means lots of matricies and index checking is expensive). Its almost like spawning a seperate process (a la microkernel) to run the job except a lot more lightweight.

Is there any equivalent to mmap, mprotect and masking in windows ?
