check.h contains the work "end", which is #defined by the compenstaion stuff; moved check.h to be the first include.

Added a 20 minute timeout to prevent deadlocks and other problems from blocking the test.

Made test longer again. (The group commit signal strangeness was preventing it from terminating...)

Towards 64-bit pageids. bufferManager can handle 64-bit offsets, but recordid.page is still 32 bit...

Test is more stringent now; it runs in roughly the same amount of time
...
becase pageFile.c is no longer using O_DIRECT.

Numerous lock manager fixes; more realistic test case for lock manager, added support for optional page-level locking.(Still need to report deadlocks back up to the caller.)

Implemented pages that store fixed sized records efficiently, and a java-style ArrayList data structure that efficiently supports (relatively) clustered, O(1) access time expandable arrays. (This will be used for the hash implementation...)

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.

Fixed regressions, major update of page / slotted interfaces in anticipation of moving LLADD towards a generic transactional page system.

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...)

bufferMananger is *really* reentrant now! (I think) However, the same thread may not load a page more than once. So, LLADD has to be altered so that it never calls loadPage() more than once per operation (more efficient), and/or pin/unpin need to be implemented. An easy way to do pin/unpin is to have them pull things out of the cache replacement list, and then re-insert them.
