I didnt say it's glibc's fault - if then it's more of the kernel's fault as most of the complexity is on that side. I said it's due to the fundamental distance between the app that makes use of it, the library and the kernel, and the resulting difficulties in getting a combined solution out. None of the parties really feels it to be their own thing. Ingo
