I have run into an issue described at
What is happening is that the GC keeps collecting map (hidden class) of a
function ("class") that is called not very often but always runs quite a
long time. As a result, the functions ends up being deoptimized and the
code runs up to 20 times slower.
Would it be possible to add some conditions/heuristics to the V8 garbage
collector to prevent this behaviour?
