The circumstances under which the problem appears are sufficiently
particular that there are tens of quick fixes available. The question
is how to fix it for real such that neither SSH nor CVS nor PCL-CVS
(in Emacs) need to work around the problem at a functionality or
performance cost.
How do non-glibc systems deal with it ? (I've only seen the
problem reported on glibc systems until now)
It seems legitimate to use stdio on stderr without having to worry about
some application that you have forked and that thus shared your stderr,
so I think the problem is that glibc's stdio does not correctly handle
the case where the file is in non-blocking mode.
