# Notes:
# - Both Helgrind and DRD use a granularity of one byte for data race detection.
# - Helgrind does detect data races on stack variables. DRD only detects
#   data races on stack variables with --check-stack-var=yes.
# - The ITC tests have been run on a 4-way 2.5 GHz Pentium 4 workstation, most
#   likely running a 32-bit OS. Not yet clear to me: which OS ? Which
#   granularity does ITC use ? And which m4 macro's have been used by ITC as
#   implementation of the synchronization primitives ?
