Simple commands like displaying help messages are where interpreter
startup time dominates the end user experience for applications
written in Python, though. For example, improvements to import system
performance tend to mostly show up there - for longer running
benchmarks, changes in startup time tend to get swamped by the actual
runtime speed, while the baseline "python -c 'pass'" mainly varies
based on how many modules we're implicitly importing at startup rather
than how well the import system is performing .

Cheers,
Nick.
