I wrote patches in this way for 1.7.8p4 and 1.7.9p2, but now I just decide
not to use fork() and move almost everything in server. Now it seems I have
another task vector for prompting in server. (it's essentially same to
the in-db support using fork(), but is more efficient).

Neither of my patches generate prompt from an invisible player. They hook on 
user inputs and outputs directed to the user. (though some of them can
examine task queue and call a verb appropriately).

Surprisingly current patch is much smaller than previous ones, that I couldn't
expect.
