dhcpd.leases question

I'm noticing DHCP leases that have the binding state "free" in my  
dhcpd.leases file that are a few days shy of being a month old.

I couldn't find the information I'm looking for in the man pages  
(maybe I missed it).  Here's my questions:

1) When, if ever, will these leases be pruned from the dhcpd.leases  

2) Do these leases count against the pool?  Say my pool runs from through  This allows me to hand out 199  
leases.  Suppose I have 198 clients with active leases, and this free  
lease in my file.  Does dhcpd reserve this lease and deny/ignore the  
199th DHCP request?  Or will this lease be pruned at that point,  
since it is free?

3) Are there any adverse side effects from this situation?
