The latter; I guessed this to be an important observation, expecting some
configuration issue.

Here a 'manual call stack':
openssh-5.8p1,

atomicio.c::atomicio6()::line 73:
This seems like an empty/closed pipe; atomicio is a "C higher order
function" given a read.

monitor_wrap.c::mm_request_receive()::line 126:

monitor.c::monitor_read()::line 478:
It happens when – with a terminal – OpenSSH request a message with
MONITOR_REQ_KEYALLOWED
again – as the first bytes of the code are identical,

This is the while loop (excuse me, please, not in monitor_read()...) The

I meanwhile have come to a strong suspicion that OpenSSH might try to
re-request the same message, while ssh2.c uses a configuration which
prohibits this.
