2a321c7547 Experimental change: On systems where it is not possible to unlink a file while one or more processes has it open (i.e. not unix), avoid closing the journal file each time the database is unlocked and reopening it at the start of each transaction.

d764c7de25 If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database.

73b64e4d2e Initial code for incremental checkpoint in WAL mode. This check-in compiles 
on unix and runs as long as you do not engage WAL mode.  WAL mode crashes and
burns.  Consider this check-in a baseline implementation for getting the new
capability up and running.
