I seem to have made a few errors that I can't figure out how 
to undo.
1) I've attached a copy of the program to the main scrapple 
page.  This should be deleted...but I don't know how.
2) I've attached a copy of the program named lrucache2.d to 
the lrucache page,  This one should also be deleted.  (I also 
attached the file with it's correct name, but this didn't 
override the prior attachment with an incorrect name.)

FWIW, there is no significant difference between lrucache.d 
and lrucache2.d, except that in lrucache2.d the tabs have been 
expanded into spaces (expand -t3 lrucache.d > lrucache2.d). 
Even then, I believe that for the version that I entered the 
tabs had already been converted to spaces.
(I much prefer to work with tabs, but apparently many people 
either prefer spaces, or have a toolchain that doesn't deal 
nicely with tabs...so I intend to be attaching a version with 
spaces, even though that's not "the preferred form of the work 
for making modifications to it".
