Another reason why Pavel should get rid of :do_login_command() and
:do_command().  The DB may run :do_command(), then parse the command, and
then display a prompt, without the need for a fork(0), which is what my MOO
currently uses.  The fork is still fast though, since it is at the beginning
of the verb, there are no variables that need to be copied.

I put a suspend(0) after the fork(0) and before the rest of the prompt code,
so if the command just issued does a suspend(0), the player doesn't get
spammed with extra prompts... It works faster than a fork(1), which is much
too long.  ...is this the best way to do it?

This is incorrect.  #0:do_command() is called when someone hits enter.  I
decided against doing this for prompts, because for some reason, 1.8.0 will
incorrectly think that clients send 2 CR's, thus making 2 prompts appear.
Yucko.
