I suppose that the whole fcgi-pm process will be restarted instead of individual
fcgi processes, correct? That'd mean a downtime of about 5 seconds which would
render it useless to me :(

I just _hope_ that lighttpd will do the right thing as the error log tells me
this when a backend server goes down:

connect failed: Connection refused on unix:/srv/webapp.socket
backend died; we'll disable it for 5 seconds and send the request to another
backend instead: reconnects: 0 load: 1
