OpenSSH + 1.1.6 strangely wedges W98SE networking

I run SSH to my two mail machines, with tunnels (port forwarding) for
ports 25 and 110. I use MS-Outlook (phoo) to read my mail from these
tunnels.  This works well for an hour or two.  After a while,
something wedges and the entire W98SE networking does not seem to work
any more until I kill one or more of the cygwin windows.  E.g., MS IE
does not get any new pages any more.  When wedged, starting a new
cygwin bash and trying some network operation sometimes fails in
unspecific ways, sometimes it tells me about the lack of buffer space
(see below).  In the SSHs, keypresses seem to get delayed, i.e. I can
type a command, see nothing, and then after typing 10 more characters
it finally comes out.

The same setup worked very nicely with the previous version of cygwin
I had installed (which seems to have been 1.1.4 with openssh 2.2.0 --
I didn't pay attention too much because it all worked so wonderfully).

Any ideas?  

(I'm a complete idiot when it comes to Microsoft APIs, so I have very
little ideas on how to narrow this down.)

Gruesse, Carsten
