Current status: the iozone-sync.sh test script is causing a segfault (sometimes at hang). Needs more testing! Segfault is at: Context.h:273. Still investigating...

Fixed a bug in objectcacher::flush_set. Branch wip-3832-oc-flushrange has been updated, and passes the accompanying iozone-sync.sh test. Needs final review and merge.
