Max num of static entries

However, remember static entries don't cause a lease to be written to 
the leases file. That only leaves syslog, and you can turn off the fsync 
on that. So you should be able to handle more static leases than 
dynamic. Also static leases go through a short cut within dhcpd, so even 
less cpu overhead.
