You're right, this is a hack.  Its funny that the problem is that the 
server is "too fast".  Where have you ever heard that before?

There is no config parameter.  Probably the easiest place to do this 
would be in the prot layer (lib/prot.c), but you *may* have to do it on 
a per command/response basis, which means touching a lot of code in 
imapd.c and index.c
