unreliable file deletion via script

[Kurt Kaufman]

I'll try:

if there is a file "BusypaymentReceipt.txt" then delete file
"BusypaymentReceipt.txt"
wait 30
if there is a file "BusypaymentReceipt.txt" then delete file
"BusypaymentReceipt.txt"
wait 30

--and see whether there are any more failures.  We can put up with an extra 
second delay, knowing that the Busy files will be deleted as expected.
I also rebuilt the standalone "anchor" with  Rev 2.5.1, just in case there 
might have been a bug in 2.0.3.  Thanks to Mark and Sarah for their 
suggestions.
