That can always be conditionalized, but...

It had been the reason I had tried it; I just wanted the accurate stat() 
information.  As such, I didn't try to convert the rest of Ruby at the time 
to support actual nanosecond-level time granularity except for as part of 
Time itself.  If you give me the go-ahead, I'll spend some free time and 
make timespec consistently used throughout the interpreter.  I didn't want 
to do the work for that, though, until I would know that it would be used
