To test mark/reset then I think it will need to call mark with a largish readLimit, transferTo to drain the input to EOF, reset, and then read or transferTo again to check that the bytes from the mark are replayed.

I did not do that so far, as we agreed to check the *new* code path, which is only executed when noting was marked (so reset plays no role). Certainly I will be happy to add another test for the use case you describe (i. e. the *old* code path), even if we all know -thanks to our knowledge of the existence of the two code paths-, that it will surely pass even with my PR in place, unless there is a bug in the *old* code path... ;-)
