As long as one isn't trying to be overly-clever in using the tools it
really isn't so bad and is about as bad as Perforce.  I don't think we
should ever use the merge command to merge commits to head from a
short-lived/non-vendor branch.  It really sounds like you have had an
unusually-bad experience with Subversion and I think we should try to
dissect that rather than writing off developing in branches.

I haven't had any significant problems with merging from head to my
branch until I reached the level of having dozens of files and
directories added in my branch originally and then looped-back from

I, like Adrian, tend to do very sort of incremental work and lots of
little commits to break up my progress (and to have lots of points to
revert to.)  It has generally been my understanding that we frown on
doing that sort of thing in head.  I don't see the point of generating
an E-Mail to everyone who reads the commit lists to add a small,
unused header file, except in very occasional circumstances.  I think
that's a great level of detail to work at in a branch.
