db: fix memory leaks
...
- sqlite3: table prevented pst gc unless close-on-exec
- statement cache wrongly disabled close-on-exec
(not a leak, just gc'd very slowly)
- limit statement cache size

db: fixed space leak in statement finalizer thread

This "fixes" the segfault in the test program, but it seems
like there must be another underlying problem.

db: fixed issues with statement finalization (don't use weak hash)
...
In some cases, statements were disappearing from statement-table
without being finalized; this makes disconnect fail.
(I was only able to produce the problem when the db lib was
instantiated in a sub custodian that is later shutdown....
like the way the rackunit gui runs the test suite.)
