I'm inserting a jl_yield so that my hungry process permits @parallel and @spawnat - but alas it doesn't look possible. It sometimes allows me to @spawnat but mostly it just crashes.
I tried: uv_async_send using multiple threads and it was about 1000 times slower than what I'm doing at present in a single thread (must be due to lib_uv joins).
If I leave the yield out it works fine :(
Not sure about this one!
