Hi Aaron,

This is amazing!  I more or less followed these threads, and
even actively participated to one, but only now I am putting all
the pieces of the puzzle together.  Thanks for your explanation,
notably by insisting on lmdb outputing architecture dependent
data, bit which really cleared things up to me!  I see how to
address the situation on kleborate side.

> Thanks for checking!

You're welcome!  Thank you so much for your help on that issue!
Have a nice day,  :)
