[New-bugs-announce] [issue43742] tcp_echo_client in asyncio streams example does not work. Hangs for ever at reaser.read()

[julian colomina]

New submission from julian colomina <julcol33 at gmail.com>:

taking the example verbatim into an ubuntu 20.04 with
 Python 3.8.5 (default, Jan 27 2021, 15:41:15)
[GCC 9.3.0] on linux

will hand indefinitely at 
data = await reader.read(100)

changing for 
data = await asyncio.wait_for(reader.read(100),5)

will always leave on timeout.
