Python class Thread has a "name" argument, which sets the name of the given thread. This name is used only internally, while there is a possibility to set this on an OS-level.

#include <pthread.h>
int pthread_setname_np(pthread_t thread, const char *name);

// FreeBSD & OpenBSD: function name is slightly different
void pthread_set_name_np(pthread_t tid, const char *name);

// Mac OS X: it only seems applicable to the current thread (no thread ID)
int pthread_setname_np(const char*);

It would be very useful if Python set the name parameter with the above pthread calls, so the user/developer could see which threads do what in ps or top.
