Actually, you can rebuild it *and* reinstall libc and libthr on a live 
system, if it's the same version of course. Already running processes 
will run off a "deleted" file (inode will still be there) and new 
processes will, since it's the same version, not notice anything is 
different.

The only downtime you will have is the time required to restart your 
application.
