 ticket:755#comment:4 mentions this problem, but that ticket is mainly
 about having deep-check continue on error. Giving information about which
 file is unrecoverable (the cap, and the filename if known) would be useful
 in more circumstances than just deep-check.

 Note that because of #625, we need a write cap to repair mutable
 files/directories. Otherwise I would suggest diminishing the cap in the
 message to a read or verify cap (since the error message channel might be
 more vulnerable to cap leakage). As it is, the user needs the write cap,
 at least for mutable objects.
