I think one of the reasons is:
"No matter how big stack is, there are always careless
code which can overflow it. 4k, 8k, 64k (hypotetically),
we still must keep stack size in mind when coding.
So, since we already are writing stack size aware code,
why not pick minimum realistically working stack size? Looks
like we can make 4k stack work, and it's naturally smallest
sensible (and in fact easiest to allocate/manage) stack for i386.
So be it, let's use 4k."
I suspect Windows went the opposite way. I bet they already went
thru several iterations of "ouch these drivers from BogoSoft
can overflow stack on nt N, let's bump up stack size for
our new shiny nt N+1".
