811bc5c710 Implemented a freespace manager that should safely allocate space, even in the face of crashes, and can reclaim unused space (unless an application opens more than one simultaneous transaction that performs allocations)
Fixed some blob bugs (by adding extra fdatasync() calls).

Began factoring out the page management code so that it is an extenstion, and a less integral part of lladd.

422198418a bufferMananger is (really!) re-entrant now, performed big refactoring to prevent deadlocks, check_transactional2 ran overnight without coring, w/ 25 threads, and 10000 allocate/write/reads per thread. (The whole test suite was run in a loop...) 2004-07-23 20:21:44 +00:00
