Sorry for the misunderstanding, but I really meant runtime as in time.
It's great that we're striving for more unittest coverage but we should 
keep an eye on the time it takes to run them.
So I ran the executables with /bin/time and std.file accounts for 60% of 
the total runtime (not including compilation). Even though file IO is 
notoriously slow this seems excessive.
