Debugging with toolbar: stopping the spawn

[Vik Olliver]

I'm debugging some code - or trying to - with the toolbar debugger. The 
problem is that I only want to break on the first  process to hit a 
function. Otherwise 3 billion other processes hit the break and flood my 
screen with debug windows.

So, how do I break on the first function break, and only on the first 
function break?
