    _______________________________________________________

Details:

When recv(1024) is called but we only have 1022 bytes, we currently wait
forever (unless the PSH bit is set or the netconn is nonblocking/has a timeout
set).

It seems like other platforms time out in this case and return 1022.

--> check how linux/windows/xBSD behave?
