I was reading between the lines here just to make sure the right answers 
are coming out.

Assuming that 56652b46f328 is still the topmost rev when you clone...

Yes.

Warning: hg technical content ahead.

The build tag changesets that Xiomara is creating are just like any 
other changeset that go into any repository:  the only file modification 
that is normally being made here is to the .hgtags file, which is at the 
top directory of every repository's tree (<topdir>/.hgtags).  This file 
is just a "list of version pointers".  For example, the top most one in 
jdk7/jdk used to contain:

     cfeea66a3fa8ca3686a7cfa2d0ce8ab0169f168d jdk7-b24
     cbc8ad9dd0e085a607427ea35411990982f19a36 jdk7-b25
     9410f77cc30c604d1caf7c9fe3a57fa19e1acbe8 jdk7-b26

The b27 tag change added the following line:

     11b4dc9f2be3523ef989a0db8459eb56b3045c3a jdk7-b27

(Note, this version uses the "long" version of the hg changeset id.  The 
short version is just the first 12 chars)

For most hg users, you should stop reading here.

Merge

Note that "clone -r ver" doesn't not actually bring the *FULL* 
repository down, only up to the version you asked for.  If you asked for 
"-r jdk7-b27", it will only bring down revision 11b4dc9f2be3, not 
56652b46f328 which is the version that actually modified the .hgtags 
files.  That was surprising to me at first.  A "hg clone -r jdk7-b27" 
followed by a "hg in" will show there is still a change (56652b46f328) 
incoming.

Hope this helps, and not confuses!
