I don't know much about RLIMIT_AS, but I know that it isn't supported on
all systems where dash runs, eg OpenBSD.  Maybe is it Linux-specific?

Anyway, it would be better if the manpage said that the -v flag may not
be implemented on all platforms.

The same could be said about ulimit -w. (I did not check the other flags).
