# enable this option.
# DPT_TRACK_CCB_STATES Enabling thos option will try to enforce strict
# sanity checking in the queue management. Rarely,

# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
# instruments are enabled. Assumed to be enabled by

# DPT_FREELIST_IS_STACK For optimat L{1,2} CPU cache utilization, enable
# this option. Otherwise, the transaction queue is
# a LIFO. I cannot measure the performance gain.
