Propellerhead: plugins should not crash the host

The idea is this: when a plug-in crashes, the host shouldn’t crash with it. Now, the developers of Reason are obviously very proud of the stability of Reason, but that isn’t the issue here. However stable or instable your host is, the notion is that a plug-in shouldn’t be the reason that host crashes.

It seems like a GREAT feature. Sandboxing is the answer and it’s something that I’ve asked to Steinberg for ages.

Well, this safety comes at the cost of performance. Just read the “Technical Note” Comment by “PaulDavisTheFirst”.
He explains the problem with sandboxing very clearly.
