Current zsh 4.3.11 has a bug which drives the CPU to 100% usage when trying several completions (in my special case it was just `ls<tab>`). While talking to some zsh gurus about this issue, they pointed me to 4.3.12 which already fixes this. I think an update would be really useful in this case. :)
Created attachment 535889 [details] Patch for the RPM Spec file to update Zsh to 4.3.12 Attached patch does the job quiet perfectly for me. I'm running a build from that since a few weeks without any issues, Let me know if I can support you maintaining the package.
If you want to apply to be a co-maintainer, I'm more than happy to accept :).
