Search for "sshstdio-6" test in the src/sanity.sh file.  It's just a
series of Bourne shell commands, and it likely depends on a few earlier
setup commands.  If you can find your way around a Solaris command
prompt, you should be able to interpret the commands you find.

Basically, and I'm going to get some of these details wrong, when CVS is
exec'd `cvs co -p somefile >logfile 2>&1', and somefile is REALLY big,
and :ext:/ssh access method is being used, then data gets lost. 
(because SSH sets its stderr to nonblocking and stderr and stdout have
been set to the same descriptor - this discussion has been going on for
years
<http://groups.google.com/group/gnu.cvs.bug/msg/8618402c11a7e981?dmode=source>).

Even the shell redirection syntax is the same on Windows.  If you want
to investigate, you should be able to.
