How about using a FIFO (maybe in /tmp) and let the daemon printf,echo,cat,...
control-msgs into the FIFO and have a perl script sitting on the other end?
Signals suck. Another advantage would be that the perl script could choose
it´s own pace and let things queue up in the FIFO. However, a FIFO only
has limited capacity. If I´d be using Haskell (http://www.haskell.org), I´d
throw in a forkIO() and would get a neatly multi-threaded solution where one
thread reads the FIFO and queues up requests while the other thread queries
him for more work -- I don´t know about threaded perl, though.
