It doesnt. Those features make sense in your spamc/sb_global_server 
configuration, but sb_bnfilter has different requirements. Its just a faster 
sb_filter, ideal for use in procmail or mua filters. 

sb_bnfilter is not a server-based solution (my apologies for using a component 
name containing the word "server" that might hint otherwise ;-)

Those features would be nice somewhere, but not in sb_filter. 


A related question: why not use ReadyExec? Its implementation relies on 
copying the filter's stdin file descriptor into the server process. This is a 
little hairy, since the server can continue to read from that file descriptor 
even after the filter process has been killed.

Nice.
