Andrea Mazzoleni 69acc1e251 Disables reallocation if a rehash is in progress. 
Be more conservative about rehash. No functional change is expected
because we were already checking rehash for blocks with updated
hash. But this way the code is simpler and easy to understand.

SnapRAID
========

SnapRAID is a backup program for a disk array.

SnapRAID stores redundancy information in the disk array,
and it allows recovering from up to six disk failures.

SnapRAID is mainly targeted for a home media center, where you have
a lot of big files that rarely change.

Beside the ability to recover from disk failures, the other
features of SnapRAID are:

* All your data is hashed to ensure data integrity and to avoid
  silent corruption.
* If the failed disks are too many to allow a recovery,
  you lose the data only on the failed disks.
  All the data in the other disks is safe.
* If you accidentally delete some files in a disk, you can
  recover them.
* You can start with already filled disks.
* The disks can have different sizes.
* You can add disks at any time.
* It doesn't lock-in your data. You can stop using SnapRAID at any
  time without the need to reformat or move data.
