What seems to happen is that rsh reads from stdin. rsh sets stdin to be
O_BINARY. However in _read (syscalls.cc) the wait flag is NOT set, so
_read returns -1 and EAGAIN. So stdin for rsh has been set to no delay,
probably by rsync.

What are the rules for inheriting flags and socket options across forks?
