@incertum Thanks.
Yes, the CI builds with "non-bundled" libs use liblua5.1 which is not as updated as the LuaJIT of the bundled lib. I have updated the CI builds, this should hopefully fix them.

@leogr I've looked and there is a test that's timing out. The test seems to be unrelated to the change and I don't recall it failing before rebasing (did it in order to be able to merge). Do we have experience of some tests failing erratically due to some other reason?
