Just wondering here: is there any way to run the machine inside a time bubble? 
That is, run its clock slower, so the passage of time inside is slower than 
the outside.

I've never seen it on the VMM software. I don't think it can be done in the 
OS. But it can easily be done by either:
 a) LD_PRELOAD / DYLD_PRELOAD intercepting clock_gettime / mach_absolute_time
 b) inside qelapsedtimer_*.cpp itself.

though this may break any tests that rely on external timing (probably the file 
time tests).
