What do you need to do exactly?  Are you going to be allocating the
memory yourself?  If so, you might want to look for wrappers around
mlock, and use the mmap gem.

If you're talking about the entire ruby VM, I would suggest compiling
your own Ruby, but modifying the memory allocators to use something like
secmalloc:
