Interesting library, but it hasn't been maintained for 10 years unless
I'm missing something.  Also it only supports concurrency on the U.B.C.
Threads kernel, whatever that is.

You can use the gdbm module for that.  It doesn't support concurrency,
but you can probably get by closing the db file between operations.
Otherwise, sqlite has concurrency.

I think you can do that on top of the gdbm module if you want to, but I'd
just use it the way it was intended:

  record = db["THISKEY"];
  if (record != NULL)
    intobuffer = extract_element(record, 4, ',');
