# Initialization logic
############################################################################
# All initialization logic must be in memory because it must execute before
# the page fill worker thread is started. Ideally this would be in some
# region that is mapped initially, but then unmapped after initialization
# is complete -- effectively freeing the memory used for the 1-time
# initialization code. That optimization has not yet been made and, as
# consequence, the 1-time initialization code takes up precious memory
# in the locked memory region.
