We should find a compromise between speed (limit the number of system calls) and the usability of Python modules. Do you have measurements that show python spending significant time on failing open calls?
No; past measurements always showed that this is insignificant, probably thanks to operating system caching the relevant directory blocks (so it doesn't really matter whether you make one or ten lookups per directory; my guess is that it matters more if you look into ten directories instead of one).
Regards, Martin
