Details:

rdiff-backup --restore-as-of $SOME_TIMESTAMP --force
/backups/rdiff-backup-source/ /some/destination

seems to loop forever (sometimes).

rdiff-backup stopped doing anything and strace revealed a pattern, I reduced
that pattern to the following loop:

open("/backups/rdiff-backup-source/rdiff-backup-data/increments/usr/src/linux-2.6.25.16-0.1-obj/x86_64/default",

O_CLOEXEC) = 9
fstat(9, {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
getdents64(9, /* 4 entries */, 4096)    = 200
getdents64(9, /* 0 entries */, 4096)    = 0
close(9)                                = 0

I have to wait until about 30G into the restore to see this so if you want
more detail just ask for it.  I have done a number of other restores without
issue, however, this one fails.

This is with 1.2.4 and the patch I supplied to correct Savannah bug 25255. I
will be retrying with 1.2.5 very shortly.
