The stock druntime gc works so long as the wasm stack is empty. 
llvm offers a shadow stack for this purpose, or I'm pretty sure 
(and Sebastiaan agrees, we've both been swamped with day job work 
but we chat every now and then a little) it'd work if we deferred 
the mark/sweep for when the wasm stack is empty.

In other words, GC.collect would always ask for new memory from 
the system as if the collection failed, but then queue it - 
javascript `setTimeout(GC.collect, 0);` would do the job. Then it 
collects when back to the event loop thus knowing the wasm work 
is paused and the call stack empty, so all stored values are 
available from memory.

Just like I said, I'm pretty swamped with work.... and when not 
doing work I have a million other things to do. I have some use 
case for webasm - it is kinda cool to put my little demo games 
online - but it isn't a high priority.
