A partial fix for ticket #3292. This fixes the original problem but there are other similar problems lurking in the code still. (CVS 5561) check-in: 055f173ab1 user: drh tags: trunk

Revise the initialization and shutdown logic so that it no longer keeps a recursive mutex allocated for the whole interval but instead releases the mutex as soon as possible. Do not reset status values upon initialization. (CVS 5559) check-in: 697fe7a316 user: drh tags: trunk
