For FreeBSD, HEAD (tip of the cvs tree) is -CURRENT, RELENG_M is a
-STABLE branch (i.e. RELENG_4 is FreeBSD-4-STABLE, and RELENG_3 is
FreeBSD-3-STABLE), and RELENG_M_m is a security/ciritcal branch (i.e.
RELENG_4_8 or RELENG_5_1 will only get critical fixes applied to them).

When the time comes for 4.9 to be released, RELENG_4_9 will be branched
off RELENG_4 a couple weeks before release, and then the
RELENG_4_9_0_RELEASE tag will be laid on that branch, which represents
what gets burned onto CDs.

Correct.  If you want -STABLE, you'll want the RELENG_4 branch, since
5.x has not been marked stable yet. 
http://www.freebsd.org/handbook/cvs-tags.html has a good summary of all
the branches and what their purpose is.  If you want a stable-ish 5.x
tree, RELENG_5_1 is probably a better choice than RELENG_5_0.  Or scan
the -current mailinglist archives, find a week where there aren't any
"-CURRENT is broken!!" threads, and checkout a copy of HEAD from that
date :)

http://www.freebsd.org/releng/ lists all the branches and their current
status (open/frozen).

In general, HEAD is okay, and if it isn't, it's usually only a single
component (say groff, or a kernel module) that's broken, and that's
fixed quickly.
