That's a good question. In fact, most modern Unix/Linux systems allow
you to use as large stacksize as you like, roughly speaking. Although
the default stakesize limit is often set to a very low value, say, 2MB,
each user can raise the limit, unless the system administrator (root)
prohibits it. So, no. That feature in question is very useful.
Some people believe that the stacksize limit should be kept low
(in other words, that you shouldn't use much stack), but, as far as
I know, nobody seems to be able to give a convincing argument for that
position. I suspect that the posision is just an inertia, a remnant
of an old habit. But, I'm ready to be convinced otherwise if somebody
has a good argument.
Cheers,
