ok, i see what u mean.

the call to the new "WaitForEvent" should be the last code in the
pj_sock_send() and no other code exept for error handeling should be there
like i see for example:

 * Send data
PJ_DEF(pj_status_t) pj_sock_send(pj_sock_t sock,
                 const void *buf,
                 pj_ssize_t *len,
                 unsigned flags)
    PJ_ASSERT_RETURN(sock && buf && len, PJ_EINVAL);

    // Return failure if access point is marked as down by app.

    CPjSocket *pjSock = (CPjSocket*)sock;
    RSocket &rSock = pjSock->Socket();

    // send() should only be called to connected socket
    PJ_ASSERT_RETURN(pjSock->IsConnected(), PJ_EINVALIDOP);

    TPtrC8 data((const TUint8*)buf, (TInt)*len);
    TRequestStatus reqStatus;
    TSockXfrLength sentLen;

    rSock.Send(data, flags, reqStatus, sentLen);

    if (reqStatus.Int()==KErrNone) {
    //*len = (TInt) sentLen.Length();
    return PJ_SUCCESS;
    } else
    return PJ_RETURN_OS_ERROR(reqStatus.Int());
