+1 on interest on having this. Back when I was attempting to port VST
to D I got asked by a Steinberg dev how I can guarantee that D plugins
will work. But I couldn't guarantee it, if a GC collection were to run
the plugin would freeze, the host would crash, and the host company
would likely get the blame. A GC-less environment would be great for
realtime plugins, I'm not sure how arrays/slices would work, but I
guess custom Array refcounted structs could be made or something.
Seems like a very badly designed plugin or plugin system if the host
crashes when a plugin freezes.
Generally, audio-plugin systems are extremely sensitive. The interface
itself is real-time performance critical and any kind of protection
against errors in the plugins comes with a run-time penalty.
A freeze in the plugin is relatively harmless and should be caught
somehow. Still - recovering from it is typically not possible without
restarting the audio thread.
