We already have the %posttrans scriptlet in rpm which implements
delaying the invocation until the end of the transaction.  While it does
not reduce the number of invocations as of FC6, having it do that
transparently too if sanely doable would be beneficial in many more
cases than just the icon cache one at hand.

By the way, wrapping the cache update in %post inside "if [ $1 -eq 1 ]"
and doing it always in %postun like it is done now would save one update
per package on upgrades already now.  And that could be applied to some
other similar cases too, not just icon cache updates, as long as the
package in question is not a "multiversion" one such as kernel.
