True.  Multi-membering just doesn't scale.  The object locking and
contention issues are brutal as these applications take on more data, users,
and job streams.  Before we moved to a 740 12-way I thought I had seen every
stinkin' ADDPFM, ADDLFM, RMVM error there was to see.  A whole bunch of new
problems cropped up on the new server -- things that seemed to suggest that
the server was faster than the member handling code.  Finding that we
couldn't perform incremental backups was the icing on the cake.

I've seen it used extensively in Island Pacific (retail/merchandising
package) and Lawson (Financials - pseudo ERP package).

I think it's one of those techniques that seems really cool when you're
designing and coding it, but really sucks when you're supporting it.
