My solution was to build ssh as Windows console app:
diff -u openssh-4.2p1-1-orig/Makefile.in openssh-4.2p1-1/Makefile.in

I create here an additional sshw.exe that sets the -mwindows linker switch. The result is still a Cygwin app that seems to work normally from the command line and works also called as background process without popping up a console window.
Two questions:
1/ Corinna, could you provide this version with next OpenSSH releases, too? Setting the appropriate property in the Subversion config to this sshw.exe, makes the SVN Clients in the Windows worlds happy. Neither Subclipse nor RapidSVN show these steadily popping up console windows anymore, nor does the command line version of Subversion behave differently.
2/ If linking a normal console app as Windows console app does not behave differently, why is it not the default? What's the real difference for Cygwin? It is still a Cygwin app and is normally listed in the Cygwin processes. I cannot say too much about the pipe and forking stuff, but something like "tar cf - *.sh | sshw spk1 tar xf -" works just normal.
