also providing persistence as a default option is also very valuable.
An additional enhancement might be to spool the current in memory hash

correct! This is at least an option to avoid the loose of the temporary
DLR data, while shutting the bearerbox down.
For "special conditions", like segfaults, we can even do this before the
OS layer forces us to die. I.e. smppbox does this for various file
system stored data. Ensuring we get at least as much as possible saved,
before going to Nirvana.
Though, not sure if we want this "store at end" and "load at start" to
be default for 'dlr-storage = internal', since it involves huge delays
in start-up time, at least on file systems that handle large amounts of
small files in a lot of directories, i.e. ext3.
We could "fork" this to a "new" type, keeping the same implementation
files gw/dlr_mem.[ch], but calling it
dlr-storage = spool-internal
to indicate that we use the spool, but keep the runtime internal
in-memory. Then we can simply pass a flag to the init function
indicating that we want loading the store and saving at shutdown.
