Needed to protect a linked list with a mutex. It's suprising that this hasn't come up before.

Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier
...
of pages, so it doesn't suggest ones that aren't already in the buffer pool unless it has to.

Removed the fixed page initialization operations, which weren't being used, and were a slow hack anyway. There is now a more-general (and efficient)

latching, as it is single threaded.

The "WARNING: Tdeinit() is aborting transaction %d" runtime message now

lists the xid of the transaction it's aborting instead of "-1".
TisActiveTransaction(xid) now returns 0 for INVALID_XID. Before the
output was undefined.

Fixed segmentation fault when a CLR with a NULLRID is encountered. I
...
don't understand why this bug wasn't triggered by linearHashNTA or
linkedListNTA, but is triggered by the new region implementation.

Documented subtle hack; TallocPage() really needs a way to set page type at recovery. Currently, this just doesn't happen, since page types are lazily set.
...
Perhaps Talloc() could handle it?

if LONG_TEST is defined, check for pinned pages on exit.
