Comment(by zooko):

 Okay, I propose that for darcs {{{mode=clean}}} is:
  1. a mode which deletes the build directory and creates a new one before
 doing darcs get --lazy. This is equivalent to the current mode=clobber and
 is nice and fast and clean. This mode should be the default.
 and {{{mode=incremental}}} is:
  3. a mode which leaves the build directory in place, equivalent to the
 current mode=update. This would be a little bit faster, but not a lot, and
 of course it is a lot messier. I would hope that people would not use this
 mode, but I'm sure somebody will want it for good or bad reasons and we
 should provide it.
 The darcs-specific third option would still be very useful for people who
 are debugging and wondering why their mode-1 {{{clean}}} build isn't doing
 what they think it should:
  2. a mode like 1. but which also passes the --no-cache option to darcs.
 This would be useful only for working-around filesystem corruption or
 darcs bugs. It would be ideal if it were triggerable through the web
 interface so that people could try it just to check if the problem they
 are seeing is due to filesystem corruption or darcs bugs. (99% of the time
 this super-ultra-clean mode would yield the same results as the normal
 mode 1. so then they would know to look elsewhere for the explanation of
 their problems.)
 I suppose it could be implemented just by coding in a darcs-specific
 {{{--no-cache}}} flag to be added to the {{{darcs get}}} command.
