Running "mdb_stat testdb" gives me the same "Resource Busy" error.
It looks like mdb.c:2941 is checking if the return address from mmap() is the same as the
hint passed in. Is there a problem with just using the mmap() return address? It looks
like the mmap() is successful but just allocating to a different place.

MacOSX and FreeBSD are somewhat dicy. If you can run the failing command ("mdb_stat
testdb") by hand, successfully, it's probably fine.
