I just found out that SPDisposecheck was finally released on MSDN Code gallery for public use yesterday.  If you write custom code against the SharePoint APIs (custom web parts, timer jobs, event handlers, etc.) you need to use this tool.  It will help you avoid coding pitfalls that can cause resource  leaks which lead to system instabilty.
