5b801b5960 Change the implementation of ActiveRecord's attribute reader and writer methods: 
* Generate Reader and Writer methods which cache attribute values in hashes.  This is to avoid repeatedly parsing the same date or integer columns.
 * Move the attribute related methods out to attribute_methods.rb to de-clutter base.rb
 * Change exception raised when users use find with :select then try to access a skipped column.  Plugins could override missing_attribute() to lazily load the columns.
 * Move method definition to the class, instead of the instance
 * Always generate the readers, writers and predicate methods.

 Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections.
 r4647@asus:  jeremy | 2006-06-19 13:07:23 -0700
 PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency.
 r4648@asus:  jeremy | 2006-06-19 13:08:40 -0700
 Pass the default allow_concurrency when instantiating new connections.
 r4649@asus:  jeremy | 2006-06-19 13:11:12 -0700
 Break out concurrent transaction tests and run them for PostgreSQLAdapter only (need to fork or system('some_test_script') for the other adapters)
 r4650@asus:  jeremy | 2006-06-19 13:42:48 -0700
 Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE".
 r4661@asus:  jeremy | 2006-06-19 15:36:51 -0700
 excise the junk mutex

44819b4717 Fixed that nested transactions now work by letting the outer most transaction have the responsibilty of starting and rolling back the transaction. If any of the inner transactions swallow the exception raised, though, the transaction will not be rolled back. So always let the transaction bubble up even when you've dealt with local issues. Closes #231 and #340.
