[Mono-list] Mono performance with llvm is faster but crashes under load

[Alexandre Faria]

When I found out about that issue with sgen (by the way, its actually a
regression), I always thought that it had to affect a lot more people.

Anyway, they fixed it before, so they should fix it again soon :)

If you want to follow it:
https://bugzilla.xamarin.com/show_bug.cgi?id=13813

That was how I was able to isolate it, but I get it in other scenarios as
well, last time they fixed it, the other scenarios also went away, so lets
hope the same!

Happy hunting... :)
