great, didn't know that.
then i guess the common problem of Node.js applications where a single
blocking task hangs the whole server is only laziness to delegate
that task out of the common thread.

if Luvit re-exposes that API, it might be easier to have a background
thread to go on secondary loop. I've done similar contraptions with
HTT.

you'd be surprised... I know single-threaded servers can be really
high performance, but there are times where the best (and cheapest!)
solution is to keep a few locked threads.
