I thought glibc did this anyway? Maybe only for stderr?

I don't think it's technically allowed to do this in a signal handler, 
though of course it's harmless in practice. Patch seems fine. Maybe you 
want to add a comment "this isn't signal-safe but it's a best-effort 
thing" to avoid signal-safety police filing bugs. ;-)
