Volatile Ruby Hash > Vash
#############################################################################
# Class: Vash (Ruby Volatile Hash)
# Hash that returns values only for a short time. This is useful as a cache
# where I/O is involved. The primary goal of this object is to reduce I/O
# access and due to the nature of I/O being slower then memory, you should also
# see a gain in quicker response times.
#
# For example, if Person.first found the first person from the database & cache
# was an instance of Vash then the following would only contact the database for
# the first iteration:
