# Here we reconstruct the following call trace:
#
#   f1()
#     f2()
#       f3()
#
# But we find that we're missing an exit record for f2() because it's
# tail-called f3(). We make sure that if we see a trace like this that we can
# deduce tail calls, and account the time (potentially wrongly) to f2() when
# f1() exits. That is because we don't go back to f3()'s entry record to
# properly do the math on the timing of f2().
#
# Note that by default, tail/sibling call deduction is disabled, and is enabled
# with a flag "-d" or "-deduce-sibling-calls".
