It requires priviledges to change at runtime and perminant adjustment 
requires access to /etc/sysconfigtab.

In answer to rth's question - my ulimit style limits are identical before 
and after, now it works, before it didnt. (and nice to know about --with-gc 
thing, or would have been before now.) - I will look into whether the system 
command for accessing the information about mmap levels requires system 
priviledges - if so then I guess no configure stuffs.)
