Ahh, as it turns out the new jemalloc in FreeBSD 10 uses a different
config string format, so I'll eventually need a uname switch anyway
(although the FreeBSD 10 release is a ways off).

Does something like this seem reasonable?

We're not currently using ovs-ctl.  Probably the closet right now is
start scripts in the FreeBSD ports tree for the db and vswitchd:


On a quick look there are some interesting bits in ovs-ctl and ovs-lib
- I'll try to investigate in more detail.
