Comment(by zooko):

 Okay here is a new version of my patch which tries harder to leave the old
 {{{mtime}}} and {{{ctime}}} alone so that it won't break the {{{tahoe
 backup}}} command.  It sequesters the new timestamps into a special entry
 of the metadata named {{{__sys}}}, and it spells out their names as
 {{{linkcrtime}}} and {{{linkmotime}}}.  In this patch, the rule of the
 caller setting metadata is simply that the caller can't touch the
 {{{__sys}}} entry, but __can__ continue to overwrite the {{{ctime}}} and
 {{{mtime}}} entries, which I think will make {{{backup}}} pass its unit
 tests again.

 Please review with consideration to whether we could apply a patch like
 this (possibly even a smaller subset of this) for Tahoe-1.4.0.
