# but will cause your program to run slower.
# clobberfree=1 causes the garbage collector to clobber the memory content
# of an object with bad content when it frees the object.
# gcstoptheworld=1 disables concurrent garbage collection, making every
# garbage collection a stop-the-world event.
# Setting gcstoptheworld=2 also disables concurrent sweeping after the
# garbage collection finishes.
# Setting allocfreetrace=1 causes every allocation to be profiled and a
# stack trace printed on each object's allocation and free.
