Should we conclude that the underlying os/zfs is not stable ?
Things don't seem to be reproducable

What Git needs here in t0050 is that stat("ä") behaves the same as stat("a¨"),
when either "ä" or "a¨" exist on disk.
The same for open() and all other file system functions.
("ä" is the precomposed form "a¨" is the decomposed form,
 typically both render to the same glyph on the screen,
 and a hex dump or xxd will show what we had.
 I just use this notation here for illustration)

Should we contact the zfs developers ?
