To use, run 'smbd -M prefork'
By default, only the smb service is preforked. 4 children are
created, and all listen for new connections. The Linux Kernel 'wake
one' behaviour should ensure that only one is given the oportunity to
accept. We need to look into the ideal number of worker children, as
well as load balancing behaviours.
To change, set:
prefork children : smb = 6
valid service names (smb in this example) match those in 'server services'.
