Normal checkout, nothing is switched, no externals.

If by child you mean a sub directory of the branch I checked out, I
don't think there is any merge info specific to a sub directory.
However, when I perform the initial merge of the entire branch with no
mergeinfo at all on the destination branch, after the 12 minute
process completes my mergeinfo looks like this. Note the merge was
from RB-25.x to RB-26.x. (I've actually merged some additional
changes from RB-25.x to RB-26.x since then, but you get the idea)
C:\work\15testing\RB-26.x>svn pl -v .
Properties on '.':
svn:mergeinfo : /branches/RB-19.4.x:7-9

I don't understand how the new merge tracking code works. We had
performed many merges in the past using svnmerge.py, but I removed
svnmerge.py's merge info before merging anything with svn 1.5.0. I
doubt that affects anything since the property names are different.
I assume all of these branches adds a lot of work, and I'd like to
understand why it recorded all of that when I only merged a single
branch. That doesn't explain the difference in time between Windows
and UNIX though.

I have already merged other changes since then. But here is a test
case where nothing needs to be merged (i.e. all changes from RB-25.x
are already on RB-26.x).
With --ignore-ancestry
Runs for a while and then spits out a bunch of skipped targets, some
conflicts and asks me to resolve. I'd send more specifics but I can't
post the path names to this list.
Without --ignore-ancestry
Runs for 14:59.79 and does nothing since no merge is necessary.
I'd be glad to perform other tests if you want me to.
