I think that this approach is too brittle to handle the advances in 
hardware and JIT technology without eventually breaking.

How about setting an absolute time limit for each test after which a 
watchdog kills it to avoid infinite looping, and then simply measure 
each test, collect the test results as well as your basic time unit, and 
then do an analysis afterwards?  The build should only break if the hard 
limits were reached.

Otherwise you may have a situation where people may be unable to build 
from source :-S
