Re: [PATCH] Linux: Implement per-thread user and group IDs


It has previously been discussed that it would be desirable for the kernel 
to have whole-process setXid syscalls 
<https://sourceware.org/glibc/wiki/Development_Todo/Master#setXid_issues>.  
Given the per-thread ID feature, would you expect any such future kernel 
feature to provide some way of exempting particular threads from the 
whole-process syscalls, or would you expect glibc to continue to use the 
signal-based mechanism in processes with threads with per-thread IDs?
