The initial author of the daemon is steve tonnessen.
How it works ?
* the daemon looks at the z3950queue table. If he finds a row that 
hasn't been spawned into z3950results, he spawns it.
* the daemon looks at the z3950results table. If he finds a row that has 
not been "forked", he forks. In the new process, he calls the 
z3950server, and when he get answers, he saves them in the marc_breeding 
table (this being my contribution)

there is an annoying bug in the spawn process : if the server name has 
spaces, he is divided in X differents server calls, which all fails.

imho, it's mandatory, as z3950 may be very slow, so we need to have 
asynchronous requests.

The daemon use koha.conf file to find DB, user & password. I don't know 
how to change this behaviour & have more than 1 .conf file.
