I has been discussed in various different threads over the years and the
last one if I remember correctly was at 2014 [1].  Carlos O'Donnel and
Martin Sebor wrote a very good analysis of Annek K [2], pointing out
flaw, potential misuses, and inefficiencies in the API.

Personalty the multithread safety issue with the contraint handler basically
render de API useless in most of the cases (even more now where multithread
become ubiquitous).  It has been proposed adjustments to its interface [3],
but even though the libc-alpha discussion have discussion about its issues
(mainly from Rich Felker).
