Were any requests retried *more* than once in any of the implementations?
It would be interesting to know if the Java implementation can retry
more than once.

For backwards compatibility (and compatibility with HC3), then we
should choose 3.
I asked on the HC mailing list, and the choice of 3 was arbitrary.

For compatibility with Java we should probably set them both to 1.

I think 1 might be the best compromise - should catch most errors.

In any case, we need to document the settings.
I'll add some text to component reference shortly.
