This change is particularly useful if one has a heavily threaded app
that uses pthread_set_name_np() to set its thread names.

This is an example of the output you get with stock GDB:

(gdb) info threads
  12 Thread 2a4041c0 (LWP 100184)  0x29e91fe3 in memset ()
  11 Thread 2a404700 (LWP 100190)  0x29e2be33 in poll ()
  10 Thread 2a404c40 (LWP 100191)  0x29ed85e7 in _umtx_op_err ()

And with this change:

(gdb) info threads
  41 Thread 0x9d80000 (LWP 100259/initial thread)  0x6a3f23ff in nanosleep ()
  40 Thread 0x9f48600 (LWP 100315/EventLoop)  0x6a38e427 in _umtx_op ()
  39 Thread 0x9f48800 (LWP 100321/ntfy)  0x6a38e427 in _umtx_op ()
