Time profiling often shows strange information

For me it's very frequent that the "entries" column in the time profile is 0, but the time taken by by that function is non-zero. The function is clearly called, so it's the "entries" that is off.

Here's a sample profiling line:

       lookupEnv         Cortex.Finance.Contract.Env                         6001           0   3.2    0.0     3.2    0.0
