In commodities.library I just rigged it so that when the OpenCnt goes to
zero, I expunge myself.  Now, how do I do that?  I guess I'll have to
check.  Anyway, that means that while testing I can easily assure that
I'm getting a new copy off the disk.

Depending on the expected use of a library, leaving such code in by mistake
isn't that bad.  Commodities.library is used for "TSR" style programs: once
open, it typically will not ever see OpenCnt == 0.

)Note that this code should NOT be included at the end of a program to force
)a "global" expunge to satisfy all the reviewers that run AvailMem to check 
)if a program frees all the resources it has allocated. Jimm will hang you for
)that :-)

No, I'll scold them.  It's *you* I'll hang for posting this code fragment ;^) ;^) ;^)
