--- Comment #8 from Michael Bacarella <michael.bacarella at gmail dot com> =

I ran into this issue recently as well.  It took a *very* long time to isol=
ate.
 I'm glad to see a patch was posted already.

I confirm on my systems that the deadlock was introduced in 2.27 and appear=
s to
resolve when the one-line patch is applied to at least glibc-2.31.
