Sometimes, writing metadata from an old (already committed) transaction may require committing a newer transaction, which also requires writing all data=ordered buffers. This can cause very long stalls on journal_begin. This patch makes sure new transactions will not need to be committed before trying a periodic reclaim of an old transaction. It is low risk because if a bad decision is made, it just means a slightly longer journal replay after a crash.
