journalCommitInterval has been added to the docs. Also a small mention of faster commit when j:1 pending. |

@dwight, in db/dur.ccp line 717, the journalCommitInterval is broken into thirds but the loop only iterates twice resulting in a total delay of 2/3 of journalCommitInterval. Is this intended? |
