Oh ok.. so it is possible to catch that. It's datastore.Timeout and
not db.Timeout, right? I was confused because when I see it in the
logs I saw: raise _ToDatastoreError(err), so I wasn't sure how to
catch it since that exception covers pretty much any issue with
writing to the datastore, not just timeouts. (Sorry, I didn't start
using python until I started using appengine, so still learning here)
example:
<class 'google.appengine.api.datastore_errors.Timeout'>: datastore
timeout: operation took too long.
