Hi David,

sleep() looks good.  I wonder whether t should take milliseconds as
other operations do - socket.set_timeout for example.  I guess it
largely depends on how long scripts generally want to sleep a coroutine
for - just a thought.

Whilst I was improving whois.nse I badly wanted sleep(), but then mutex
came along and this turned out to be a better solution since the aim was
to protect a resource from use by more than one coroutine at a time - in
this case, a connection to a whois service.
On my TODO list is a script for brute forcing VNC auth which will need
sleep and also an HTTP/HTML spider in which sleep could be useful in
avoiding a ban for aggressive crawling.

So yes, a useful addition indeed.
