'dbm' hash table software

[jordan at nike.UUCP]

	The reason I am suspicious is that after creating a large hash
	table and apparently not getting any errors, certain entries in
	the database don't exist, for no reason I understand.

dbm was a hack to get 4.2 out the door -- 4.3 has a new implementation
that does the right thing (i.e., dbm_open() returns a DBM *) and the size
restriction was raised to 4096 bytes ... however, I think there
are still some inconsistancies in the man page.
