How to disable new thread / stream messages in gdb?

Question

I am debugging a Gtk + application and I am getting a lot of messages like this:

[New Thread 0x7fffde152700 (LWP 11142)] [Thread 0x7fffde152700 (LWP 11142) exited] [New Thread 0x7fff967fa700 (LWP 11143)] [Thread 0x7fff967fa700 (LWP 11143) exited] [New Thread 0x7fff967fa700 (LWP 11144)] [Thread 0x7fff967fa700 (LWP 11144) exited] [New Thread 0x7fff967fa700 (LWP 11145)] [Thread 0x7fff967fa700 (LWP 11145) exited] [New Thread 0x7fffde152700 (LWP 11146)] [Thread 0x7fffde152700 (LWP 11146) exited] [New Thread 0x7fffde152700 (LWP 11147)] [Thread 0x7fffde152700 (LWP 11147) exited] [New Thread 0x7fffde152700 (LWP 11148)] [Thread 0x7fffde152700 (LWP 11148) exited] [New Thread 0x7fffde152700 (LWP 11149)] [Thread 0x7fffde152700 (LWP 11149) exited] [New Thread 0x7fffde152700 (LWP 11150)] [Thread 0x7fffde152700 (LWP 11150) exited] [New Thread 0x7fffde152700 (LWP 11151)] [Thread 0x7fffde152700 (LWP 11151) exited] [New Thread 0x7fffde152700 (LWP 11152)] [Thread 0x7fffde152700 (LWP 11152) exited] [New Thread 0x7fffde152700 (LWP 11153)] [Thread 0x7fffde152700 (LWP 11153) exited] [New Thread 0x7fffde152700 (LWP 11154)] [Thread 0x7fffde152700 (LWP 11154) exited] [New Thread 0x7fff967fa700 (LWP 11155)] [Thread 0x7fff967fa700 (LWP 11155) exited] [New Thread 0x7fffde152700 (LWP 11156)] [Thread 0x7fffde152700 (LWP 11156) exited] [New Thread 0x7fffde152700 (LWP 11157)] [Thread 0x7fffde152700 (LWP 11157) exited] 

I was almost never interested in these posts, and they make reading the rest of the output more difficult. How to disable these messages?

You can disable stream events during gdb startup:

 set print thread-events off
