Are there any plans on adding something that might >help? Or is it all too system dependant? Software Verification will be providing a Memory inspection tool for Ruby. It will initially be available on Windows. Initial research work has been completed. The software tool will show allocations sites, references, garbage collections, loiterers, cycles etc - all the stuff you need to identify problem areas in Ruby code. Implementation will be later this year. I can't give you a date at this time because I don't know one. http://www.softwareverify.com Stephen -- Stephen Kellett Object Media Limited http://www.objmedia.demon.co.uk RSI Information: http://www.objmedia.demon.co.uk/rsi.html
