# Some explanation of why tests have been excluded above:
#
# Test 008 was pulled because it contained a race condition leading to
#          spurious failures.
#
# Test 049 was pulled because it caused a kernel fault.
#	http://tracker.newdream.net/issues/2260
# Test 232 was pulled because it caused an XFS error
#	http://tracker.newdream.net/issues/2302
#
# This test passes but takes a LONG time (1+ hours):  127
#
# These were not run for one (anticipated) reason or another:
