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.
