I'm not sure about ASLR. But at least it should be possible to randomize
the loading address the first time that the booster is started (at boot
time, maybe?), or the booster can be killed and restarted from time to
time. Also, the loading address of the application executable could be

I'couldn't find any, but the difference is so huge that you don't need
any benchmarks :-) Just watch this:
The second time, the applauncherd hasn't had the time to initialize a
new booster process, so a cold start-up happens instead.
