Description

e.g. child_process.spawn and os.cpus() can be very slow calls that cause lag on the main thread. Would it make sense to perform async versions of these calls that run on a worker thread?

Research direction

Start by investigating the child_process.spawn and os.cpus() entry points and how their current libuv calls run on the main thread. Determine the scope and API design for worker-thread-based asynchronous versions, then verify that the proposed calls no longer cause main-thread lag.
