Great!  Many thanks for this.  Please give it a bit more pounding, and I'd 
encourage other users of dreload to also try it out.  The code is definitely 
far simpler than the original dreload, but since I don't understand that code 
too well, I'd like to tiptoe a bit on this issue.  If it survives a bit of 
pounding and discussion, I'll definitely be glad to put it in.

Obviously, I'll also test it myself and think about it a bit.
