boilerplate: define a reasonable default stack size
PTHREAD_STACK_MIN can be quite large (128k) on several architectures,
and small on others (16k). Instead of using a multiple of such value
which tends to be overkill in the former case, define
PTHREAD_STACK_DEFAULT = max(64k, PTHREAD_STACK_MIN) as the reasonable
default size.
NOTE: this is only a default value, applications needing a larger
stack size should override it into the thread attribute descriptor by
a call to pthread_attr_setstacksize().
