(Cross-posted from the boost list.)

Doing an SVN update instead of a full check-out would reduce server bandwidth considerably (and reduce test cycle time).

I wonder if Ticket #4916 <https://svn.boost.org/trac/boost/ticket/4916> has something to do with the decision (not) to trust Subversion.  '--force-update' doesn't wipe out intermediate files as regression.py clearly intends it, making it act like '--incremental'.

I think someone should fix #4916, make '--force-update' the default, and see what that does to server load.

Then, bring back source browsing if we can.
