Named Pipes not working after massive Cygwin update/install

Hi,

I just updated/installed every conceivable Cygwin package on my XP
box, and named pipes are no longer working.  Anyone else experiencing
this?

A few days ago (prior to updating Cygwin), I had two instances of a
two-week old version of mencoder happily talking to each other 
over a named pipe.

Now (after updating Cygwin), neither that old version nor a fresh one
I just built (again, after updating Cygwin) will talk to each other
over a named pipe.

Here's a simple example of something that doesn't work:

        ================ Cygwin Terminal #1 ================
        [Jim Solomon@orion ~] $ mkfifo pipe
        [Jim Solomon@orion ~] $ ls -lF pipe
        prw-rw-rw- 1 Jim Solomon None 0 Mar 18 21:32 pipe|
        [Jim Solomon@orion ~] $ cat < pipe
<Ctrl-c>
        [Jim Solomon@orion ~] $ 
        ================ Cygwin Terminal #1 ================
        
        ================ Cygwin Terminal #2 ================
        [Jim Solomon@orion ~] $ ls -l > pipe
<Ctrl-c>
        [Jim Solomon@orion ~] $ 
        ================ Cygwin Terminal #2 ================

It makes no difference whether I start the "writer" or the "reader"
first -- in both cases I get no output in either terminal, so I
Ctrl-c'ed them both to get the prompt back.

I'd appreciate any help you folks can provide.

"cygcheck -s -v -r > cygcheck.out" is attached.

Cheers,
WB
