I should clarify the first sentence. With a bunch of external machinery to
support a distributed transaction model, it's possible to run BDB across
machines, but Elephant doesn't have any of it so can only use the built-in
shared memory locking facility. There was some talk a year or two ago a
BDB does not work across multiple machines, its transaction support relies on a
shared memory region to handle locking so any shared memory architecture (with
multiple CPUs) works fine but separate machines and a NAS device don't work.

in parallel. The documentation [1] says that "Transactions will ensure there is
no interaction between processes.". Does this mean that I have to use the
common methods to open the store (open-store '(:BDB "path-
