Comment 3 for bug 1655795

I've noticed two separate issues, one is that `xtigervncviewer -listen` doesn't accept multiple incoming connections; I reported it in https://github.com/TigerVNC/tigervnc/issues/400.

The other one is that sometimes it doesn't exit cleanly, preventing new viewers from launching. Unfortunately I haven't found a reliable way to reproduce it, it only happens some times.

If upstream accepts those to be bugs, I guess we can recommend tigervnc in epoptes, and leave it up to the tigervnc debian maintainer to backport the fixes to debian stretch?
