Setting a thread sensitive Breakpoint

I just came across the problem that I needed to break at a function just in case this function is executed in one specific thread.

In Visual Studio 2008 (and also earlier) you can achieve this via Breakpoint filters:
1.) Right click on the Breakpoint and click on Filter...


2.) Now specify the thread id you want to break in...


In windbg you can achieve it like this:

Instead of typing:

bp MyModule!MyClass::MyFunction+MyOffset


type:
~ 13 bp MyModule!MyClass::MyFunction+MyOffset

to break in just if this function is executed in thread with id 13
