Oh, possibly.  That does mean that the process can use up arbitrarily
large amounts of memory just by forking, which kind of limits the
usefulness.

I don't think you will necessarily be toast; when it reaches the limit
things like brk() will just start to return ENOMEM, which libc should
handle.  Of course most programs have probably not been tested in this
domain and so will die.
