Vlad, I need to push the patch first and investigate this problem
second. I understand somebody wanted to not bother with the sync
in the ticket, but it is not a priority for me.
Please revert fiber_sync() changes asap and update the tests, so
that I can push the patch. We can talk about fixing
box.session.sync() later. My problem with the patch is that you
make a partial fix (box.session.sync() is still broken) and use
fiber local storage for something that has little to do with a
fiber.
I'm sure there are acceptable ways to fix box.session.sync().
I'll be happy to discuss them once we've done with the current
patch.
