Hi Guido,
hi all,
everything works perfectly in 16.0-CURRENT and stable/15. Would it be 
possible to officially MFC this patch[2] to stable/15, given that 
15.0-RELEASE has already been published?

The patch has been tested in 16.0-CURRENT for couple months now, and an 
MFC to stable/15 is possible by pulling in only one other commit[1] as a 
prerequisite. It also appears that it no longer breaks the ABI[3] and 
was even reworked to increase robustness[4].

There is still sufficient time to test this enhancement in stable/15, 
and it would be a good candidate for inclusion in 15.1-RELEASE.
