My theory is that the 64k size is so low that some platforms ignore the `pthread_attr_setstacksize` call.  Now that we changed it to 128k, it actually triggers a problem where the ASan reporting facilities overflow the stack.  Although it seems weird that ASan's error reporting would require 64k of stack...
