While you could easily dynamically alocate/copy this data, it opens the 
doors for much bigger problems:  A caller could pass so much data to DoS 
the kernel (can be fixed), or push the callee into a low memory situation 
(mmap/malloc failing), exposing other problems.

And seriously, why?  Just for some shell scripts which then will be 
incompatible with the rest of the world?  Not a good idea.
