Looking at an strace of nmap, it seems it opens a bunch of
sockets, puts them into non-blocking mode, calls connect on them
(which will return EINPROGRESS), and then uses select(2) to wait
for them (in a loop, until all have either been accepted or
rejected). select(2) accepts a timeout value,

Why ?
Socket.select() will wait _at most_ 100 msecs. If a socket gets

you might not get the full

You could implement a `dup()` method. `dup` is already used for
