Concatenating changesets

[blr at robertsr.us]

I really like the idea of logically mapping changesets to defect
fixes or features.  But I also like to commit early and often in
my own working repository.  I've tried the "Concatenating
multiple changeset into one changeset" from the Tips and
Tricks (http://www.selenic.com/mercurial/wiki/index.cgi/TipsAndTricks),
but it has a couple of problems.

Most importantly, the final clone takes just over a minute with
my code base.  That makes our old CVS faster in most cases.

Is combining changesets a bad idea (amd I still thinking in CVS),
or are there other, faster ways to do this with hg?

Thanks,
