Benchmark the time (in seconds)
to compute the normal form of an expression.
The expression is created by an I/O action (first parameter).
This avoids the sharing of the normalization process between multiple
runs of the benchmark and provides more flexibility, e.g.,
to read benchmark input data from global variables.
