At the moment, yes. But in the ideal world, everything would be
(optionally) nonblocking. So open(O_NONBLOCK) would return a file
descriptor before the system knows if the requested pathname refers to a
valid file.
Or maybe we should introduce a new "socket" family: AF_FILE. You would
do:
f = socket.socket(socket.AF_FILE, socket.SOCK_STREAM, "rwb")
f.setblocking(False)
try:
f.connect(pathname)
except socket.error as e:
if e.errno != errno.EINPROGRESS:
raise
