The idleling guile process uses too much cpu #3
Description
The guile process currently reads from /dev/zero indefinitely, causing it to use too much cpu.
I don't know how else to keep the process alive, but this is not ideal.
Reading from an empty named pipe causes guile to not listen on the socket until something is written to the pipe, after which it exits on EOF.
Reading from /dev/null causes guile to exit immediately.
