 * A disk based hash table for large amounts of data

 MUTEX is a ACE_Thread_Mutex or ACE_Null_Mutex or similar
 DATA must implement:
 copy constructor
 assignment (operator =)
 default constructor
 destructor (seems to not deallocate right without)

 KEY must implement
 specialize TWlib::tw_hash<KEY *> (if does not exist in the headers already)
 EQFUNC: implement the operator(KEY *) for eqstr struct (see above_...
 copy constructor
 destructor

 ALLOC Allocator style class for allocating DATA objects as they are pulled off
 the disk
