cygwin-1.5.16-1: FIFOs broken

- Subject: cygwin-1.5.16-1: FIFOs broken
I have a client-server application written in Perl that reads and writes
using FIFOs. It works fine under cygwin-1.5.15-1, but fails under
cygwin-1.5.16-1 because it cannot read from the FIFO.
To test this, open two shells. In one shell, type:
cd /tmp
mkfifo FIFO
cat <FIFO
In the other shell, you can send text to the first shell using:
cd /tmp
echo YOUR TEXT HERE >>FIFO
After you're done, just ^C in the first window.
Under 1.5.15, the above works fine.
Under 1.5.16, no text goes through the FIFO. Further, the echo command
hangs, and will not terminate with ^C. A 'ps' shows an 'O' for this
stuck shell. You have to do a kill -9 on the shell to terminate it.
