Debugging Threads

[Robert Klemme]

Hi all,

people have problems debugging threads. What do others think about,
setting abort_on_exception to true if ruby's command line option -d is
set? That would terminate the whole process if there is an exception in a
thread, which some regard helpful.

What do others think?

This is a good idea, and because it's a good idea it's already implemented
