I made slight modifications to the mdbm package and am using that as a dbm
for many programs, including news, on my System V machine.  It appears that
the overhead in mdbm associated with opening a database is high enough that
not a great deal is gained generally, although it does "feel" faster.  My
question is what is kept in the dbm database?  It appears to be little more
than an offset into the LIB/history file.  Are the LIB/history.d/[0-9] files
necessary or useful with dbm?  I deleted the LIB/history.d directory after
getting dbm running, with no apparent problems.  It appears that the dbm
database is nothing more than an index by message-id into the LIB/history file.
