... you can instead of the previous patch, add a constructor here that just
sets namebuf to "main" with strcpy.

How about just a static initializer

   static __thread char namebuf[PTHREAD_MAX_NAMELEN_NP] = { 'm', 'a', 'i', 'n', 
'\0' };

or is there some interaction with __thread that makes that undesirable ?

This would break here:

    if (namebuf[0] != '\0') {
        return namebuf;
    }

and every thread would have "main" as the name, because static 
initializers for __thread apply to all threads.

Thanks,
