Computer speed?!  It depends mostly on how much diskspace you have
available and what size 'unsigned int' your C compiler supports.

Assuming it's a fairly normal 4 byte type you can go theoretically up
to about 4 billion (4,294,967,296) objects but most people will run
out of disk/swap-space long before that since each object takes up at
least one sector and the minimum sector size is 256 bytes (I think).

Oh, and there's also the issue that DGD needs to be able to 'seek' in
the swap file, so your OS may hit its head somewhere at the 2 or 4GB
swap file size.

Hope that helps,

Erwin.
