I thought about doing so, as the output of ps really looks bad.
Unfortunately, I found only very nasty ways.
On older host's, we could try to expand or strip down the environment in a similar
way as is used it tt. Then, names could be placed into stub-(stack?)-page.
Nasty, but it could work.
An even worse case is a host using stack-randomization. We need a pointer in the
host poining to stub-pages. If the host has left a "hole" above the stack, would
we have to "exec" until accidentally we get a stack starting at upper address-range
limit?
