If we are reporting many similar exceptions we will call
circleci.rollcage.core/build-trace
many times for exceptions withidentical or very similar stack traces. By memoizing
circleci.rollcage.core/rollbar-frame
we can avoid some expensivere-work on the most common stack frames and thereby reduce the memory consumption (and I/O profile) of this library.
Rough testing suggests that this change can yield a >20x reduction in memory consumption when many similar exceptions are thrown.
