A quick idea:
Can't elephant keep a list of lambda forms to be executed at commit
and perhaps a list of lambda forms to be executed at abort. Then
instead of directly caching it, you can make a lambda form that does
the caching, and push it to the list of commit actions. This will
defer execution of it to a safer time.
