I've reviewed your patch at sourceforge.net.

I don't see a chance of getting garbage characters at the end of the
name string:

memcpy(td->td_name, name, sizeof(td->td_name) - 1);
td->td_name[sizeof(td->td_name) - 1] = 0;

In case name is shorter than sizeof(td->td_name) the full name string
including terminating '0' byte will be copied.
In case name is longer than sizeof(td->td_name) the string will be
copied partly and a terminating 0 will be added. So your name will be

Garbage is only possible if your Name string is not zero terminated and
shorter than sizeof(td->td_name);

If you call NutThreadCreate this won't be possible? Have I missed
