(Whiteboard: [MemShrink])

In bug 676189 we found that slop bytes caused by jemalloc rounding up allocation request sizes were wasting 10--15% of SQLite's memory. The SQLite folks have written a new version with an option SQLITE_PAGECACHE_BLOCKALLOC that avoids most of this waste (and the remainder is handled by bug 678977). We should pull this in as soon as the new SQLite release (which will be 3.7.8, IIUC) comes out.

Hmm, bug 678977 comment 22 indicates that SQLITE_PAGECACHE_BLOCKALLOC won't be an acceptable fix.

I'll close this, see comment 1.
