FYI, I have encountered the following bug with ruby\_debug breakpoints:

A breakpoint will break in any file being executed for which the current  
line number matches the breakpoint line number and the breakpoint  
filename is a suffix of the filename of the file being executed.

Thus, e.g., if a breakpoint is set for “server”, the breakpoint will  
incorrectly break if the designated line number is encountered in  
“httpserver”.

I have submitted a bug report to the project at RubyForge with a  
suggested fix.
