It should be easy to catch this problem. Order balance is verified
exactly to cents and if there is any difference, the property
'order.paid_in_full' is evaluated false.

Use this simple patch for logging: http://pastebin.com/HKWbCZBR
You can also select well known option "Verbose logs" for payments in
livesettings ("Add extensive logs during post." EXTRA_LOGGING)

Then use filtering in the log what is not paid exactly.
   grep paid_in_full satchmo.log

If you confirm very small balances in the log and Chris will agree,
the method '_paid_in_full' can be simply changed in Satchmo.
I think that payments rounded up to whole number can be silently
accepted for some currencies, namely rounding up, but I do not know
and really I do not want to suggest anything about payments.
