Comment 4 for bug 1181146

Agreed; the vast majority of bare "raise" calls in Swift are checking some attribute of the error (e.g. "err.errno in (X, Y, Z)" or "'some string' in err.message") to swallow some subset of the errors. There's only a handful that are logging right now, so those are the ones that should get patched up.

Hopefully the Eventlet folks release soon...
