# Some notes about the singleton behavior of this class.
# 1. the constructor does not return a singleton reference!
# 2. there is a seperate function called singelton() which will return a
#    singleton reference
# this change was introduces with ResourcePool 0.9909 to allow more flexible
# factories (e.g. factories which do not require all parameters to their 
# constructor) an example of such an factory is the Net::LDAP factory.
