> OS threads are expensive: an operating system thread typically reserves a megabyte of stack space and takes roughly a millisecond to create.
It's typically less than a hundred kilobytes and (on the systems I've benchmarked using std::thread) it takes 60usec (wall time in userspace) to create and destroy a thread.
Threads have gotten so fast that paying the async function coloring price makes very little sense for most software.
