Wrong question.  The question is whether adding support for very large,
or arbitrarily large (hence swappable) arglist+environment makes the
common case (i.e., 1 page) significantly slower, or otherwise negatively
impacts the kernel (e.g., resource starvation).  We won't know until someone
implements it.  If you are interested in pursuing this, and seeing
it done the "right" way, see this post by Jamie Lokier from Mar 2000,
along with the surrounding thread:
