One question. Does GC work with Adam's druntime for wasm?
I haven't actually written one yet, so it leaks if you don't
pay attention yourself. But I have a plan that should work: you
do the setTimeout(collect, 0) so it runs when the event loop is
idle. Then the wasm stack is empty so you can scan pure memory.
IMHO, D's GC need a second thread
This isn't true, it never needs a second thread, even on normal
desktop.
The problem with GC on wasm is the webasm stack is opaque. You
can have the compiler output a shadow stack or my plan of
scanning when it is empty. Either should work but I haven't had
time to implement anything.
