No, it is. A single thread running a recursion-intensive program can use many 10's of K's of stack; and 10's of K's per thread is not "cheap threads". GHC has had a dynamically growing stack for many years, starting at 4k and redoubling when exhaused; the stack size limit is a bug checker and nothing else. Stefan
