wxLin message queue freezing for >60s

The thing cleared up meanwhile. It was a wrong use of the select() command:

bool Server::DataAvailable(long tv_sec)
{
  fd_set fdset={1, m_Sock};
  timeval timeout={tv_sec, 0};
  return select(m_Sock+1, &fdset, NULL, NULL,
   LONG_MAX==tv_sec?NULL:&timeout)>0;
}

instead of

bool Server::DataAvailable(long tv_sec)
{
  fd_set fdset;
  FD_ZERO(&fdset);
  FD_SET(m_Sock, &fdset);
  timeval timeout={tv_sec, 0};
  return select(m_Sock+1, &fdset, NULL, NULL,
   LONG_MAX==tv_sec?NULL:&timeout)>0;
}

HTH,
V.
