Yes, that seams the case.

I have reproduce the gen_tcp:connect in  http_transport.erl to get the time
for that request. The time values for gen_tcp:connect and http:request
(Asynchronous) aproximately same.

So my argument is,
Asynchronous request should return immediately and whatever the results
(reply/error OR timeout) received should return later rather than hanging at
that possition.  Am I wrong ?

Follow up the attached test with below reqults.

RESULTS:

1> c(connecttest).
{ok,connecttest}
2>
2> connecttest:test_url().
 Time for gen_tcp:connect request 189017815 microseconds ConnectRes={error,
