| | | | | - Also carry allow_concurrency value through to connection adapter (for postgresql)

* Introduce synchronization around connection pool accessNick2008-08-291-13/+36
| | | | | | - use new active support Module#synchronize - allow_concurrency now switches between a null monitor and a regular monitor (defaulting to null monitor to avoid overhead)

| | | | | | So far so good, tests still run clean. Next steps: synchronize connection pool access and modification, and change allow_concurrency to simply switch a real lock for a null lock.
