The default is 64MB on i386, 512MB on amd64; that's where the
getrlimit value comes from unless it's been explicitly reduced
somewhere. The kernel MAXSSIZ sets the value of the hard limit for
RLIMIT_STACK for proc0, and everything else inherits that. All
setrlimit calls for RLIMIT_STACK are explicitly clamped to MAXSSIZ, so
there's no way to set that value higher than the kernel limit, and no
way for getrlimit to report a value higher than the real limit.
