If you want to push the scalability limits of your code, you really
want to reduce the \b contexts/stack_size item. Its default value
-is 128 (in KiB), while our Chord simulation works with stacks as small
+is 8 (in MiB), while our Chord simulation works with stacks as small
as 16 KiB, for example. For the thread factory, the default value
is the one of the system, if it is too large/small, it has to be set
with this parameter.
