Okay I'm trying again with Bazaar 1.17 (bzr-svn 0.6.3 - not 0.6.3dev
as before)...

In trying other things with the previous bazaar 1.16.1 (bzr-svn
0.6.3dev) I tried 'svn-import' instead of 'branch' and defined the
branch patterns in subversion.conf for that repo UUID.

'bzr svn-import' didn't bring in any of the .../projects/projectx/*
revisions despite showing the patterns from the subversion.conf that I
specified - it did still pull in about 25000 revisions from before
those branches though.

In addition to not pulling all the branches I wanted I hit an even
bigger showstopper. Once it finished copying revisions into the 2a
repository it tried to repack and got a memory error (the single pack
it was repacking was ~4GB with ~25,000 revisions).

After the failed pack I could "bzr heads --all" and see the branches
it did pull in. "bzr init foo & bzr pull --overwrite -r
revid:REVID_FOR_TIP_OF_FOO -d foo" got me branches for all of these
and they look correct.  However I cannot pack the repo.

I'm trying this sequence again with 1.17 so I'll let you know if the
problem vanishes.  If I fail the repack again I'll rerun with
performance monitors and see where process memory gets to at the point
it aborts - I note from event logs that virtual memory was not
exhausted so I expect the process address space was exhausted.

I'm aware this repacking memory issue probably isn't a bzr-svn problem
as much as an indication of problems repacking a largish 2a repo in
Win32.  However I mention it here (and to you Jelmer specifically) as
I suspect other Win32 users of svn-import with medium to large repos
might hit it so you might want to watch out for it.
