This could be compensated by slowing down the system time so that 1 system
second takes 10 real seconds. Whatever variance there is should not reach
this order of magnitude. This could probably be achieved with a simple
patch to the relevant glibc functions. Or maybe it's easier to patch the
An optimist thinks that this is the best possible world.
A pessimist fears that this is true.
