4.9-RC #3 : Which release is this??

[jhampton at sscglobal.net]

I recently update my box via cvs stable-supfile. Now when I do a uname -a
I get "FreeBSD 4.9-RC #3". Shouldnt I see something like 4.9-STABLE ? What
does RC mean? By the way this is for a prodution machine so stability is a
factor. Thanks
