Using integer values as keys leads to poor load balance.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start 50 nodes.
2. For key from 0 to n
3.   write(key, value)
4. Watch the load distribution.

What is the expected output? What do you see instead?

Load should be balanced throughout the nodes. Instead, only four nodes 
accumulate the load.

What version of the product are you using? On what operating system?

r536. Linux.

Please provide any additional information below.

Using stock configuration.

The hashing for keys, which are integers, was disabled. We enabled it as of 
r537.

This fix essentially broke range_read for my application. In various places it 
is claimed that scalaris stores keys in lexicographical, is this feature only 
supported in scalarix?

Also, read_range now generates a exception:

I fixed the badmatch problem. The open-source version does not support
lexicographical ordering.
