Descrizione
First seen in https://github.com/JuliaLang/julia/pull/49745, but to summarize, InProcessMemoryMapper calls mprotect many many times on mmaped memory, so many times that for a non trivial workload we go past /proc/sys/vm/max_map_count leading to a ENOMEM error.
I haven't created a non julia reproducer but it should be possible.
