Problem seems to be related to object scale.
Different problems are visible at different scales.
For this blend, Calculate Holes option seems to work correctly at any scale if Threshold is increased to 0.0000001.
Increasing the threshold to 0.0000001 and this problem goes away, nevertheless this needs investigating.
Yes. Another thing here is : we have to manually type "000001‘ after the default editable "0.0" value. And, if clicking on arrows, it only allows increasing / decreasing by increment of 0.01, instead of 0.0000001), which is not that easy to control as well imho. So, maybe it is reasonable to set a higher scale for this value for easy tweaking.
With defaults, BMesh boolean now works with this example. Also, the UI is set so entering very small values isn't such a problem.
Closing.
