[ANN] Localmemcache-0.4.0: A persistent key-value database based on mmap()'ed shared memory.

Hi,

I am happy to release localmemcache 0.4.0 today. This version mainly
aims to make the API more complete and less confusing to users (thanks
for your feedback!). The version jump is mostly because of
incompatible API changes and that some of the adjustments required the
the database format to change which means that old .lmc files cannot be
read by 0.4.0.

API CHANGES
===========

- New class for storing Ruby objects directly instead of just strings:
LocalMemCache::SharedObjectStorage

- New instance methods: .clear() [clear/empty hashtable], .size(),
.each_pair(), .random_pair()

Cleanups:

- LocalMemCache's class methods .clear() and .clear_namespace() have
been renamed to .drop(). The :repair parameter is now called :force.
- LocalMemCache.check_namespace() has been removed (use .check()
instead).

EXAMPLE
=======

require 'localmemcache'
# 1. the memcached way
# $lm = LocalMemCache.new :namespace => :viewcounters
# 2. the GDBM way
#$lm = LocalMemCache.new :filename => "./viewcounters.lmc"
# 3. Using LocalMemCache::SharedObjectStorage
$lm = LocalMemCache::SharedObjectStorage.new :filename => "./viewcounters.lmc"
$lm[:foo] = 1
$lm[:foo]
$lm.delete(:foo)
