Why is it limited to debug builds?

Please add the generated files (pmemobj0.log.match, ..., and pmemobj4.log.match) to local .gitignore.

Code quote:

pmemobj$UNITTEST_NUM.log.match

Maybe it does not have to be deleted assuming it is ignored by git? To be considered.

Code quote:

if [ "$BUILD" = "debug" ]; then
	rm pmemobj$UNITTEST_NUM.log.match
fi

	mv pmemobjXXX.log pmemobj$UNITTEST_NUM.log

Please create a common.sh file for this group of tests so you don't have to copy this bit over.

if [ "$BUILD" = "debug" ]; then
	grep "Explicit transaction abort" pmemobj$UNITTEST_NUM.log > pmemobjXXX.log

Why does it have to be conditional?
