Hi, I brought one of my boxes up to date from an early 2.3.0 state today and was a little surrised to find flwm and synergyc core dumping somewhere in a thread call (pthread_suspend_all_np in both cases). Then I noticed that the box still had the threading symlinks pointing to libc_r, so I switched to to libthread_xu and everything works fine now, so it looks like it's no longer safe to switch to libc_r.
