A dependency loop could be detected when ordering the transaction.
Packages participating in the loop must be installed essentially
"at the same time". Can't we do something like this, then?

1) %pre of B, then C
2) unpack B and C
3) %post of B, then C

Should work no worse than the current solution, IMO.
(scriptlet-to-executable requires would always work, at least)
