> Another "favourite" issue that shows up often when you use strace like this is e.g. excessive include paths - running strace on MRI Ruby with rubygems enables and lots of gems pulled in is a good way of seeing that in action - like this zip problem it's an example that seems totally reasonable when the number of gems is small, and that first becomes apparent when you test with lots of gems, and look at what's actually happening under the hood. When you add e.g. Python's standard library as a ZIP to the Python search path, the thing will open/read/read/read/close that file approximately a gazillion times on startup. That's OK on Linux/Unix, where that is fairly cheap. Guess which OS doesn't like that pattern at all?
