--- Comment #19 from .san <san+sourceware at smederijmerlijn dot nl> ---
Hi all,

It is probably not common knowledge that the Unreal Engine 4, a popular and
very advanced real-time 3D creation tool used for game and other real-time
rendering applications, is affected by the behavior described in this ticke=
t.=20

The patches, version 4, as provided by Chung-Lin Tang reduce the startup ti=
me
of UE4 from 200+ seconds to ~15 seconds.=20

Not sure if it should affect the priority on this ticket but I wanted to let
you all know that there are real world examples of this issue and having a =
fix
out would be a very significant improvement for Game Developers on Linux.=20

Considering an opt-in behavior change, toggle-able with an global/environme=
nt
variable, would allow us devs to use upstream glibc again.

Cheers!
.san
