Is Rails Logger Thread Safe?

Is Rails Logger truly not Thread Safe?
http://log.kares.org/2011/04/railslogger-is-not-threadsafe.html

This seems like an issue that should have been picked up quite a long
time
ago. I just set config.threadsafe! in my config/application.rb and my
log
output from rails server has completely disappeared.

If the logger is not thread-safe, I cannot help but wonder how much of
the
Rails core is not thread safe. Is config.threadsafe! even a viable thing
to
use in Rails?

It looks like someone tried to fix that around a year ago

What version of rails are you using ?
