Comment:

 This is quite serious. `(##sys#fudge 6)`, `(##sys#fudge 16)` and the C
 runtime functions `milliseconds()' and `cpu_milliseconds()`, including all
 variables that are set to results of these are affected. The `tcp` unit
 uses them for timeout calculations as does the scheduler (which is
 compiled in fixnum mode).

 Damn.
