I strongly advise you against trying to game the system in this way.
You'll lose much more time than the 1.5 hours dealing with the
fall-out. I just timed a CACAO build on my new desktop machine
(4-core), which took less than 6 minutes. Hotspot builds, like the one
you did, take a bit longer because of the large amount of C++ code (12
minutes on this machine).
