Isn't it possible to check before extending the stack whether
there's room for the planned extension?

As I said I don't think there is much that perl could do to
salvage the running program; but if possible it should at least
throw an error along the lines of "Deep recursion in regex in
file foo.pl line 42" and, ideally, proceed to die in an orderly
manner (global destruction and all that).
