dmakogon added a comment.

As suggested by @nikic I replaced the `NumTripCountsComputed` and `NumTripCountsNotComputed` with `NumExitCountsComputed` and `NumExitCountsNotComputed` respectively. They are updated during computations made for single exits. It relieves us of the need to compute exact exit count for the loop just to update the named statistic and thus the recursion cannot happen anymore.
