Not really... 8-)

In a Linux box, look for clone(2) - all you need to know is there :

	man clone

	man ulimit

        ulimit [-SHacdefilmnpqrstuvx [limit]]
               Provides control over the resources available to the  shell  and
               to  processes started by it, on systems that allow such control.
                   ^^^^^^^^^
               The -H and -S options specify that the hard or soft limit is set

               ...

               -s     The maximum stack size

	I understant : "the maximum stack size per process." Am I right ???

My 2 cents
