Originally I was more thinking the language interpreter startup time,
which I expected to be the problem. In PII 400Mhz/512M/W2k/Cygwin this
$ time python -c "exit;"
takes average of 1.5 sec (real). To run 3 commands in series, it would
1.5 x 3
hence my question if --batch could be considered.

OK, Where can I learn more about the "serve" plugin?
Could the "serve" plugin be included in the Core? This sounds like it
would help people using Cygwin version of python.
