I would much rather see us implement A. It makes things more obvious to the
user. We aren't asking them to do any multiplication to look at how many
requests they can handle at once. This will also cut down on the number of
bugs filed. I am mostly thinking of Unix, where threads are reported through
ps. If people specify 6 processes to start, but ps reports 120 have been started,
they think it is a bug. In reality, Linux is just reporting all the threads as if
they were processes.
Also, sticking with A makes us translate better from 1.3 to 2.0. I know this isn't
a concern for most people, but it would be nice for our users.
