Better put a placeholder in the cache and then do a oneWayBecome
afterwards.
cache at: key ifAbsent: [
cache at: key put: (placeholder := Object new).
cache at: key put: (newValue := (self build: anObject)).
placeholder oneWayBecome: newValue ].
And if you want it bullet proof, you use Meta's MessageRecorder :)

Looks like an interesting trick, but don't you then end up with the
value true in some of your meta-models? Wouldn't it make more sense
to use nil instead?
