Hi,

A large part of the build time is being consumed by tests … could we
separate those phases so a package whose tests succeeded once does not
have to be rebuild just because its package got garbage collected?

(⇒ keep the test result (boolean) longer than the build result)

Keeping just a boolean that says whether the tests for a given hash
succeeded could make that pretty cheap and it could avoid half the build
time for packages that got garbage collected before.

Best wishes,
Arne
